Nats Jetstream: consuming a message without subscription causes deadlock in the consumer #206

Closed mymdz closed 2 months ago

mymdz commented 2 months ago

Steps to reproduce:

  1. Generate multiple operations: A and B
  2. Subscribe to a specific subject (A) using UserController, without UserSubscriber implementation
  3. Send a message to B. A warning will be printed: Received message for not subscribed channel 'B'. Message will be ack'd.
  4. Send a message to A - nothing happens

There is a deadlock because of writing to nil channel
