Error: operation has timed out

[rasheed-asahi]

Frequently getting this error "Error: operation has timed out" in my sails logs. The error message points to this location "socket.io\dist\broadcast-operator.js:181:30".

Can somebody help me with this?

Error from sails log given below:
Error: operation has timed out
at Timeout._onTimeout (socket.io/dist/broadcast-operator.js:181:30)
at listOnTimeout (node:internal/timers:557:17)
at processTimers (node:internal/timers:500:7)

Node Version:16.10.0
Socket.io Version: 4.5.4
Sails Version: 1.5.3

operation has timed out can be returned when sending a packet to multiple clients and expecting an acknowledgement (here in the code), but not all clients respond in the given delay:

io.timeout(5000).emit("hello", "world", (err, responses) => {
  if (err) {
    // some clients did not acknowledge the event in the given delay
  } else {
    console.log(responses); // one response per client
  }
});

Hi @darrachequesne, the timeout() call is mandatory even when calling socket.emit() on a remote fetched socket emitting only to that single specific socket? Because I see the same error in that case... Is considered broadcasting that too?

I think this may be related: #4558

Yes it is. I will make it clearer in the documentation.

I added .timeout(1000) and solved.
