Why do I get 'unknown delivery tag' error when I requeue a message in rabbitmq the second time?

Question

In my application, after I get a message from rabbitmq, I push the message to a client, and wait for its ACK message, if the client doesn't reply with a ACK after some time, I requeue the message in rabbitmq with basic.reject with requeue being true.

This works fine for the first requeue operation, but after I requeue the same message for the second time, the channel is closed abruptly. From the server log, I get this error:

{amqp_error,precondition_failed,"unknown delivery tag 2",'basic.reject'}

I gather this is because the message has been removed from the queue. Why is this happening?

I had similar error

Error: Channel closed by server: 406 (PRECONDITION-FAILED) with message "PRECONDITION_FAILED - unknown delivery tag 1"

My solution was to assert channel with enabled option durable channel.assertQueue(queueName, { durable: true });
