Running flask-socketio and python-socketio, how to fix "Server.emit() got an unexpected keyword argument 'broadcast'"?

[karenlaw]

I am running flask-socketio 5.4.1 and python-socketio 5.11.4. I am getting this error:
TypeError: Server.emit() got an unexpected keyword argument 'broadcast'
I am not sure how to fix this, can someone point me to the right direction?
Here is the traceback:

Remove broadcast=True in line 90 of app.py.

Got it. I missed that, I didn't realized I wasn't looking at the latest doc.
