I had to upgrade my websockets version when I got this error:

Error creating proxy connection: create_connection() got an unexpected keyword argument 'additional_headers'

I upgraded from 12.0 to 14.1 - perhaps you would like to add to the requirements.txt

I think this has been changed to 14.1 already.
