cannot import name '_request_ctx_stack' from 'flask' about flask

You are not using the latest Flask-SocketIO. The version that you are using is only compatible with older versions of Flask. At some point around Flask 2.2 they have changed some implementation details regarding user sessions in a backwards incompatible way.

Flask-SocketIO 5.3.0 and up have adapted to their new way, so switch to that and hopefully you should be fine.

I suggest that you start by closing this issue, since you do not seem to experience the original issue anymore.

The whole point of having the allow_unsafe_werkzeug flag is to prevent you from doing something that is almost always a bad idea. I would consider switching to a production server instead of continuing using Werkzeug. Try Gunicorn, for example.

Finally you seem to have a problem uploading files, which is completely unrelated to the allow_unsafe_werkzeug flag. You suggest that uploads work without this flag set, but that cannot be, since without the flag the web server wouldn't start at all. Once you collect enough information about your file upload issue, you may consider writing a discussions post on the Flask repo or Flask-SocketIO repo, whichever is the project you need help with.

Thanks @miguelgrinberg let me try that out

Will give feedback here instead of opening a new issue incase something occurs, I had tried adding the allow_wezbierg flag to true and it worked fine but I could not upload files for some reason

Am getting the following error
RuntimeError('The Werkzeug web server is not ' backend | RuntimeError: The Werkzeug web server is not designed to run in production. Pass allow_unsafe_werkzeug=True to the run() method to disable this error.
If I add this flag to the socketio.run function uploading files fails,

I've been in this loop for almost three days now, not sure whether its a combination of the package versions that's wrong or what it is really.
