Issue:
TypeError when connection is closed in connect()
I have the same problem then #185 but I think, I can reproduce it.

When you close a connection in the connect() method of a WebsocketConsumer, it works fine with daphne but uvicorn raises a TypeError 

```

I created this branch on the django-channels-example repository: https://github.com/ostcar/channels-examples/tree/uvicorn-test

All I changed was, that the websocket connection is always closed: https://github.com/andrewgodwin/channels-examples/compare/master...ostcar:uvicorn-test

I think the problem is, that you call `websockets.WebSocketServerProtocol.recv()` before the websocket connection is open so `websockets.WebSocketServerProtocol.connection_open()` was not called. In this case the attribute `transfer_data_task` is still None. So when `websockets.WebSocketServerProtocol.recv()` calls 

```python
yield from asyncio.wait(
                    [pop_message_waiter, self.transfer_data_task],
                    loop=self.loop,
                    return_when=asyncio.FIRST_COMPLETED,
                )
```
it tries to await `None` what causes the exception.

I don't know, if this is a but in the websockets package or if you should check `self.closed` before calling `self.recv()`

Discussion:
I'm also facing this issue - when connections are closed, several errors pop up. Doesn't affect operation, but quite concerning nonetheless.

Full stack trace (may be mixed with other errs...):

Still facing this issue.
Okay - can someone break this issue down to something smaller, not involving channels.
Also does the issue replicate on both websocket implementations or just one?

(Use `--ws wsproto` and `--ws websockets` to switch between the two implementations.)
Hi, I think we have the same problem in our app:
```

```
@sergicolladosopra Okay, with Channels or something else?

What's the smallest possible codebase someone can reduce this down too, so that I've got a good place to start digging from?
Here is a minimal example without using django:

```python
class Application:
    def __init__(self, scope):
        self.scope = scope

    async def __call__(self, receive, send):
        if self.scope["type"] != "websocket":
            return

        while True:
            # what for the 'websocket.connect' event.
            await receive()

            # Close the connection
            await send({'type': 'websocket.close'})
```

To test it, you have to start it with an asgi server an open a websocket connection.

With daphne:
```

```

The error seems to be, that the `while True:` loop does not break. But when I look into the django channels code, it seems, that django channels also does not close the loop.

The loop in django channels is here: https://github.com/django/channels/blob/03d221792e6881477911728615a6d51ec9fab73b/channels/utils.py#L45

The `close` message is send here: https://github.com/django/channels/blob/03d221792e6881477911728615a6d51ec9fab73b/channels/generic/websocket.py#L226

An exception, that could break the loop is raised when `websocket.disconnect` is handled: https://github.com/django/channels/blob/03d221792e6881477911728615a6d51ec9fab73b/channels/generic/websocket.py#L241
Channels allows to call `close()` during connection handshake in `connect()`, but in example above with wsproto it doesn't, neither does websockets protocol which doesn't handle `websocket.close` (closed_event is set) in `asgi_receive`.

I took a look into [`websockets` docs](https://websockets.readthedocs.io/en/stable/design.html#opening-handshake) which says:

> calls process_request() which may abort the WebSocket handshake and return a HTTP response instead; this hook only makes sense on the server side;

and seems like it's implemented on the web servers and maybe also in channels' middlewares.

So calling close() when connection handshaking is not a right thing to do?
I also have this issue, using uvicorn 0.8.6 and channels 2.2.0. My channels consumers don't call ``.close()`` anywhere. I'm getting various errors whether I use `wsproto` or not. The problem doesn't occur with Daphne. The app works fine in the browser but I am concerned about all the tracebacks.

In `websockets/server.py`, the handshake stops at this line in `WebSocketServerProtocol.handshake`:

```
        if self.state != State.CONNECTING:
            raise CancelHandshake()
```

At that point, `self.state` is `State.CLOSED`. It was set to CLOSED here:

The `exc` variable in the above traceback is:

```
ConnectionAbortedError(10053, 'An established connection was aborted by the software in your host machine', None, 10053, None)
```

I also see this:

```
('%s ! failing WebSocket connection in the %s state: %d %s', 'server', 'CLOSED', 1006, '[no reason]')
```

I tested on Linux (WSL) and I get basically the same traceback.

Happy to provide any additional info to troubleshoot this.

The thing that would help most with progressing this would be to try to replicate the issue in a plain ASGI application, or in Starlette, or something more minimal than installing Channels.

If anyone's able to reduce the issue like that then I'd be very happy to dig into it.

Is there any update or workaround for this?  I can post more info about what I'm seeing, but it looks like the connection closes and things are fine browser side, but if I call .close() in the .connect() function I end up with type errors in the logs.  Having stack traces in the logs is obviously not ideal, but it would help to clarify that's the extent of the issue...
My workaround is to open the connection and close it immediately.
Turns out this error was being logged -- and ignored -- in the unit-test suite already.

I'm not 100% confident in my reading of the [ASGI-to-websockets spec](https://asgi.readthedocs.io/en/latest/specs/www.html). The _Websockets_ spec (as cited in the `websockets` codebase) suggests it's wrong to call `recv()` before a successful handshake -- which is why this stack trace is logged. But the _ASGI_ spec doesn't say anything.

For all I know, all real-world ASGI applications call `recv()` before the handshakes completes, whether that's ideal or not. So my pull request [#704] makes `recv()` return an error message -- the same one that would be returned after unexpected disconnect.
> If anyone's able to reduce the issue like that then I'd be very happy to dig into it.

@tomchristie ping? I have reduced the issue by enabling logging in Uvicorn's own test suite. I also submitted pull request #704 with a sketch of a fix. Are you still keen to dig into it? :)
Is there any way at all I can be of any more help? I've helped diagnose, I've authored a pull request, I've written helpful notes on all issues I could find that seemed relevant. I'm doing my best, and I'm prepared to do better. Please direct me.

Our project experiences this stack trace >35,000 times per day. I worry that _real, as-yet unknown_ errors are hiding among all those duplicates.
> My workaround is to open the connection and close it immediately.

This has been the only way so far to silence the uvicorn errors we are seeing.
Hi all,

I'm taking a look at this given pings on #704.

I was able to reproduce the `TypeError` from OP using this setup.

```python
async def app(scope, receive, send):
    assert scope["type"] == "websocket"

    # Pull up first recv message.
    message = await receive()
    assert message["type"] == "websocket.connect"

    # Reject the connection.
    await send({"type": "websocket.close"})
    # -- At this point websockets' recv() is unusable. --

    # This raises the `TypeError` on the server.
    message = await receive()
    # But we would expect it to succeed and return this:
    assert message["type"] == "websocket.disconnect"
```

Client:

```python
$ python -m asyncio
>>> import websockets
>>> await websockets.connect("ws://localhost:8000")
websockets.exceptions.InvalidStatusCode: server rejected WebSocket connection: HTTP 403
```

The client sees the 403 after we sent `websocket.close`, which is expected, but it's the server that's having an issue with the extra `TypeError` there.
maybe this is relevant too:

https://github.com/aaugustin/websockets/pull/670
I'm also facing this issue - when connections are closed, several errors pop up. Doesn't affect operation, but quite concerning nonetheless.

Full stack trace (may be mixed with other errs...):

Still facing this issue.
Okay - can someone break this issue down to something smaller, not involving channels.
Also does the issue replicate on both websocket implementations or just one?

(Use `--ws wsproto` and `--ws websockets` to switch between the two implementations.)
Hi, I think we have the same problem in our app:
```

```
@sergicolladosopra Okay, with Channels or something else?

What's the smallest possible codebase someone can reduce this down too, so that I've got a good place to start digging from?
Here is a minimal example without using django:

```python
class Application:
    def __init__(self, scope):
        self.scope = scope

    async def __call__(self, receive, send):
        if self.scope["type"] != "websocket":
            return

        while True:
            # what for the 'websocket.connect' event.
            await receive()

            # Close the connection
            await send({'type': 'websocket.close'})
```

To test it, you have to start it with an asgi server an open a websocket connection.

With daphne:

```

The error seems to be, that the `while True:` loop does not break. But when I look into the django channels code, it seems, that django channels also does not close the loop.

The loop in django channels is here: https://github.com/django/channels/blob/03d221792e6881477911728615a6d51ec9fab73b/channels/utils.py#L45

The `close` message is send here: https://github.com/django/channels/blob/03d221792e6881477911728615a6d51ec9fab73b/channels/generic/websocket.py#L226

An exception, that could break the loop is raised when `websocket.disconnect` is handled: https://github.com/django/channels/blob/03d221792e6881477911728615a6d51ec9fab73b/channels/generic/websocket.py#L241
Channels allows to call `close()` during connection handshake in `connect()`, but in example above with wsproto it doesn't, neither does websockets protocol which doesn't handle `websocket.close` (closed_event is set) in `asgi_receive`.

I took a look into [`websockets` docs](https://websockets.readthedocs.io/en/stable/design.html#opening-handshake) which says:

> calls process_request() which may abort the WebSocket handshake and return a HTTP response instead; this hook only makes sense on the server side;

and seems like it's implemented on the web servers and maybe also in channels' middlewares.

So calling close() when connection handshaking is not a right thing to do?
I also have this issue, using uvicorn 0.8.6 and channels 2.2.0. My channels consumers don't call ``.close()`` anywhere. I'm getting various errors whether I use `wsproto` or not. The problem doesn't occur with Daphne. The app works fine in the browser but I am concerned about all the tracebacks.

In `websockets/server.py`, the handshake stops at this line in `WebSocketServerProtocol.handshake`:

```
        if self.state != State.CONNECTING:
            raise CancelHandshake()
```

At that point, `self.state` is `State.CLOSED`. It was set to CLOSED here:

I also see this:

I tested on Linux (WSL) and I get basically the same traceback.

Happy to provide any additional info to troubleshoot this.

The thing that would help most with progressing this would be to try to replicate the issue in a plain ASGI application, or in Starlette, or something more minimal than installing Channels.

If anyone's able to reduce the issue like that then I'd be very happy to dig into it.

https://github.com/encode/uvicorn/issues/244#issuecomment-482893968
Is there any update or workaround for this?  I can post more info about what I'm seeing, but it looks like the connection closes and things are fine browser side, but if I call .close() in the .connect() function I end up with type errors in the logs.  Having stack traces in the logs is obviously not ideal, but it would help to clarify that's the extent of the issue...
My workaround is to open the connection and close it immediately.
Turns out this error was being logged -- and ignored -- in the unit-test suite already.

I'm not 100% confident in my reading of the [ASGI-to-websockets spec](https://asgi.readthedocs.io/en/latest/specs/www.html). The _Websockets_ spec (as cited in the `websockets` codebase) suggests it's wrong to call `recv()` before a successful handshake -- which is why this stack trace is logged. But the _ASGI_ spec doesn't say anything.

For all I know, all real-world ASGI applications call `recv()` before the handshakes completes, whether that's ideal or not. So my pull request [#704] makes `recv()` return an error message -- the same one that would be returned after unexpected disconnect.
> If anyone's able to reduce the issue like that then I'd be very happy to dig into it.

@tomchristie ping? I have reduced the issue by enabling logging in Uvicorn's own test suite. I also submitted pull request #704 with a sketch of a fix. Are you still keen to dig into it? :)
Is there any way at all I can be of any more help? I've helped diagnose, I've authored a pull request, I've written helpful notes on all issues I could find that seemed relevant. I'm doing my best, and I'm prepared to do better. Please direct me.

Our project experiences this stack trace >35,000 times per day. I worry that _real, as-yet unknown_ errors are hiding among all those duplicates.
> My workaround is to open the connection and close it immediately.

This has been the only way so far to silence the uvicorn errors we are seeing.
Hi all,

I'm taking a look at this given pings on #704.

I was able to reproduce the `TypeError` from OP using this setup.

```python
async def app(scope, receive, send):
    assert scope["type"] == "websocket"

    # Pull up first recv message.
    message = await receive()
    assert message["type"] == "websocket.connect"

    # Reject the connection.
    await send({"type": "websocket.close"})
    # -- At this point websockets' recv() is unusable. --

    # This raises the `TypeError` on the server.
    message = await receive()
    # But we would expect it to succeed and return this:
    assert message["type"] == "websocket.disconnect"
```

Client:

```python
$ python -m asyncio
>>> import websockets
>>> await websockets.connect("ws://localhost:8000")
websockets.exceptions.InvalidStatusCode: server rejected WebSocket connection: HTTP 403
```

The client sees the 403 after we sent `websocket.close`, which is expected, but it's the server that's having an issue with the extra `TypeError` there.
maybe this is relevant too:
