Need help. proxy webSocket - Error: read ECONNRESET

[yesongling]

Is this a question?

Using HPM to proxy webSocket. But once webSocket server shut down, HPM server will catch this error and crash.

The root cause seem to be an error event has not been handled. But I dont know where to handle it.

Env
Node: 10.8.0
HPM: 0.19.0
System: Mac OS 10.13.6

Error logs & config
events.js:167
throw er; // Unhandled 'error' event
^

Error: read ECONNRESET
at TCP.onread (net.js:660:25)
Emitted 'error' event at:
at emitErrorNT (internal/streams/destroy.js:82:8)
at emitErrorAndCloseNT (internal/streams/destroy.js:50:3)
at process._tickCallback (internal/process/next_tick.js:63:19)

Fixed.
Handle error on upgrade callback can fix it.
