Edit: I was reading more bytes then available in the Node socket buffer, thus I was never completing the job

Anyone ever got a problem where a coroutine is just stuck at a return statement?

private suspend fun readUnsignedInt(): Number {
  val buffer = read(4) ?: throw IllegalStateException("Expected 4 bytes to be available")
  val number = buffer.readUInt32BE(0)
  println(number)
  return number
}

I can see the number printed to the console, and then nothing, stuck forever.

Seems like a bug inside the Node.js wrappers. Could you please create a ticket in youtrack and assign it on me?

[Edoardo Luppi]

@Artem Kobzar what was happening is this.
I'm reading n bytes from the TCP net.Socket

socket.read(nBytes)

If nBytes is greater than socket.readableLength, read returns null.
What I was doing was:

val buffer = socket.read(nBytes) as? Buffer?

if (buffer != null) {
  continuation.resume(buffer)
}

Are you sure it's a bug on your side? This seems more an error on my side

[Artem Kobzar]

Oh, in this case, yes, the bug is on your side.
