Explanation: https://websockets.readthedocs.io/en/stable/project/changelog.html#backwards-incompatible-changes:~:text=second%20parameter%20of-,connection,-handlers%20is%20deprecated

My first thought is that this happens through a package on which we depend (which in turn depends on websockets) - possibly FastAPI. In that case, I think an upgrade of that package might solve the issue.
