RabbitMQ Message deduplication working in localhost but not in CloudAMQP

Question

I installed RabbitMQ with the message deduplication plugin on my localhost and deduplication worked out of the box without me having to explicitly specify an exchange.

The moment I opted for CloudAMQP and installed the Message Deduplication plugin, deduplication stopped working. Is there something else I need to do for message deduplication to work in production under CloudAMQP.

Below is the NodeJS code I used that worked perfectly in localhost but not working in production:

    .....

         channel.assertQueue('test_queue', {
                    durable: true,
                    arguments: {
                        'x-message-deduplication': true,
                    }
                }),
                channel.prefetch(1),
                channel.consume('test_queue', 
         handleIncomingMessage)


  ......
        handleIncomingMessage(message){
                channel.ack(message);
        }

Then when sending messages to the queue I used the following:

   channel?.sendToQueue('test_queue', { ...data }, {
        headers: {
            'x-deduplication-header': `${data.id}`,
        }
    })

The above code worked perfectly in my local rabbitmq instance with no duplicate messages but not working in CloudAMQP. Duplicate messages are happening in cloudamqp. Really weird.

What else do I need to do please?
