Thanks for the review

The type hint was added so that the ignore could be removed.

Thanks for the review

The type hint was added so that the ignore could be removed.

Unfortunately it trades one ignore for another so I took it back out

Error: homeassistant/components/websocket_api/connection.py:162: error: Incompatible types in assignment (expression has type "Union[Dict[str, JsonValueType], List[JsonValueType], str, int, float, None]", variable has type "int")  [assignment]
Error: Process completed with exit code 1.

Messed around with this for a bit and since it's only going to get to that path on garbage input, the ignore makes sense here

Not to go off topic, but is there a way for an average HAOS user to take advantage of these memory leak fixes in the frontend without setting up a dev environment? The memory leaks have made my system unstable.
Thanks
