python-socketio and python-engineio versions are incompatible

[adrianvisovan]

Rasa version: 2.3.4

Socket.IO Javacsript client version: 3.1.2

Operating system: osx

Issue: Connecting to Rasa 2.3.4 using socket.io is not possible due to the versions incompatibility of python-socketio and python-engineio.

According to the official python-socketio documentation, if the version of the python-socketio is 5.X, then the version of python-engineio should be 4.X.

Solution could be to increment the version of python-engineio dependency to at least 4.0.0

Is this fixed in 2.4.0?

We are also awaiting a fix for this. Our project uses pip-tools so we can't upgrade Rasa until dependencies are compatible
