socket .io has gone through many breaking changes recently as they went from v2 to v3 to v4 is a short period of time. You should check which version of socket .io that node-red-contrib-socketio is requiring vs which version is installed. I recently came across this error when implementing socket .io in my video streaming node and changing the constructor to satisfy a cross-version solution.
