RabbitMQ in NestJS, error on both Producer and Consumer

Question

I have the following app https://github.com/rengthp/nestjs-rabbitmq-microservice

But I get on Producer :

[Nest] 6156 - 04/03/2021, 13:28:53 [ClientProxy] Disconnected from RMQ. Trying to reconnect. +25469ms [Nest] 6156 - 04/03/2021, 13:28:53 [ClientProxy] Object:

{
  "err": {
    "code": 406,
    "classId": 50,
    "methodId": 10
  }
}
 +3ms

and on Consumer:

111ms
[Nest] 1180   - 04/03/2021, 13:22:31   [Server] Disconnected from RMQ. Trying to reconnect. +1058ms
[Nest] 1180   - 04/03/2021, 13:22:37   [Server] Disconnected from RMQ. Trying to reconnect. +6006ms
[Nest] 1180   - 04/03/2021, 13:22:43   [Server] Disconnected from RMQ. Trying to reconnect. +6017ms
[Nest] 1180   - 04/03/2021, 13:22:49   [Server] Disconnected from RMQ. Trying to reconnect. +6026ms

What could be wrong? the server is working...

Answer 1

This error came up because you re-declare an existing queue with different parameters. The solution is simple. The option queue for both producers and consumers must be the same and all option parameters must be the same.
