I was able to fix my CORS issues using the `handlePreflightRequest` referenced in https://github.com/socketio/engine.io/issues/279#issuecomment-585578251 but I couldn't use the latest changes implemented for engine.io v4 in **socket.io (2.3.0)**.

My apologies @Apollon77, let me clarify. Perhaps I'm misunderstanding the issue but I was suggesting to try the change that I referenced on the socket.io server to see if that...

I just started seeing this error today as well.
