TL;DR: after upgrading to flask_socketio from 5.3.2 to 5.3.5 in #404, something broke with websockets and we were unable to send payload bigger than ~500kB. Reverting to 5.3.2 didn't work, because flask_socketio depends on python-socketio and python-engineio, which actually are the cause of the issue, and even with flask_socketio 5.3.2 the latest version of those was pulling.
This PR temporarily reverts flask_socketio to 5.3.2 and also pins python-socketio and python-engineio to the last known working version.
Next steps:
[x] figure out the exact version of python-socketio/python-engineio that breaks things (#443)
[x] upgrade to that version (#443)
[x] check if there is an issue upstream about it, and if not report it
[ ] once the issue upstream is fixed remove the pins for python-socketio/python-engineio and upgrade flask_socketio (#451)
