My app uses ws in Express server to serve WebSocket. I have seen a lot of errors in production:
RSV2 and RSV3 must be clear
/app/node_modules/ws/lib/Receiver.js:184:18getInfo
/app/node_modules/ws/lib/Receiver.js:153:16startLoop
/app/node_modules/ws/lib/Receiver.js:139:10add
/app/node_modules/ws/lib/WebSocket.js:142:22_ultron.on
events.js:96:13emitOne
events.js:188:7emit
_stream_readable.js:176:18readableAddChunk
_stream_readable.js:134:10Readable.push
net.js:547:20onread
It seems to happen occasionally to some of my users, and I have never been able to reproduce it in my local environment.
What can I do to further investigate the root cause of this error?
