### Reproduction

First, following the quickstart for Templates until it gets to LangSmith deployment:
1. `pip install -U langchain-cli`
2. `langchain app new my-app`
3. `cd my-app`
4. `langchain app add pirate-speak`

Then, since I don't have access to LangServe, follow the template README for docker deployment:
5. `docker build . -t my-langserve-app`
6. `docker run -e OPENAI_API_KEY=$OPENAI_API_KEY -p 8080:8080 my-langserve-app`

Results in error:
```

```

I also tried the `research-assistant` template and got a similar `get_input_schema` error. 

Am I missing a setup step?
