From past few days, i am getting the below error when i try to run the example python websocket flexible-app-engine application (https://github.com/GoogleCloudPlatform/python-docs-samples/tree/master/appengine/flexible/websockets). It use to work before but now when i run, i see the below error.
I dont see this issue when i run locally using - "gunicorn -b 127.0.0.1:8080 -k flask_sockets.worker main:app".
I see this issue only when i deploy in google cloud.
