TypeError: Cannot set property 'readyState' of undefined resurfaced?

Hi, in the current version (7.2.1) an older bug similar to #1564 seems to have reappeared:

node_modules/ws/lib/websocket.js:837
websocket.readyState = WebSocket.CLOSING;
TypeError: Cannot set property 'readyState' of undefined
   at Socket.socketOnClose (node_modules/ws/lib/websocket.js:837:24)
   at Socket.emit (events.js:333:22)
    at Socket.EventEmitter.emit (domain.js:485:12)

The issue was caused by an invalid usage of ws, so my guess is that you are doing the same mistake. Are you using gun.js? If so see #1606 and #1606 (comment) in particular.

Please fill the issue template, it's there for a reason, and create a test case to reproduce the issue.

Yup, you're right. I do not use gun.js, but there were two WebSocket servers created for the same http server.
Maybe ws can check if there is already an instance attached to a http server?
Closing this as it is not a bug.

It should, see 3641266. I'm not sure why it is not detected in your case.
