[VeNoMouS]

Calling a disconnect sometimes results in the following exception, which you can't trap...

python-engineio==3.13.0

I see websocket-client is a requirement in setup.py

   extras_require={
        'client': [
            'requests>=2.21.0',
            'websocket-client>=0.54.0',
        ],

but it works without it, and i dont see reference to it in the code??

It's referenced in engineio ...

Thanks, I think I can handle these exceptions to prevent the crash.
