Hi there! We hit this issue on an internal code analysis project that uses Jedi internally. We worked around it by [patching `jedi/inference/filters.py` to cleanly handle the `KeyError`](https://github.com/Datadog/jedi/commit/92d0c807b0dcd115b1ffd0a4ed21e44db127c2fb), but this...

> I'm interested to find out what you're using Jedi for internally. Sure, I can sort of answer this: we want to detangle a large monorepo, so we're generating dependency...

I'm not sure of that -- I just know that the stack trace we see is very similar (though not identical), and my commit, linked above, appears to fix it.

👋🏻 We think we're seeing this too, with 5 middlewares, on: ``` fastapi==0.109.2 starlette==0.36.3 anyio==4.3.0 ```
