The channel was closed: AMQP close-reason, initiated by Peer, code=503

Hi,

We are facing the following issue:

System.InvalidOperationException: The channel was closed: AMQP close-reason, initiated by Peer, code=503, text='COMMAND_INVALID - unknown exchange type 'x-delayed-message'', classId=40, methodId=10 9

I understand from previous discussions that this error can occur when the rabbitmq-delayed-message-exchange plugin is not enabled. However, in our case, we've confirmed the plugin is enabled, yet we're still encountering the issue. Do you have any suggestions on what else might be causing the problem?
