Tried with both 3.1.0 and 3.2.0

Could you include the full stack trace? Also, what version(s) of socketio do you have installed? npm ls socket.io will tell you (actually, the entire npm ls dependency tree output would be useful).

We have had this before https://github.com/RuntimeTools/appmetrics/issues/241

sjanuary commented 7 years ago

We had to close #241 as there wasn't enough information but it looks like we can now identify the probe that is causing the issue which should help.
