How to rebind/consume queue from channel?

Question

I am using amqplib to transfer messages in my node.js server.

Here is my code to listen on queue:

channel.consume(queue, handler1, { noAck: true })

Now, I want to update the consumer to listen the same queue

Like this:

channel.consume(queue, handler2, { noAck: true })

I try to unbindQueue or deleteQueue but don't know why the error Unhandled rejection IllegalOperationError: Channel closing is thrown
