I see. The `/xd/deployments/` path is constructed as such:
```
Paths.createPath(Paths.DEPLOYMENTS, containerName, moduleName)
```
whereas the `/xd/streams` path is:
```
Paths.createPath(Paths.STREAMS, streamName, moduleType, moduleName, containerName);
```
So it appears that we need to include (at minimum) the module type in the `/xd/deployments` path.
