Magento 2 Type Error occurred when creating object: Magento\Framework\MessageQueue\Consumer\Config\Data

Question

I've gone through the Megento Message queue process. I learned and tried one sample module in my local. but while run the queue:consumers:list command I am facing the following error.

In AbstractFactory.php line 131: Type Error occurred when creating object: Magento\Framework\MessageQueue\Consumer\Config\Data

For your further reference here I've added all my consumer related XML files. I hope this information are sufficient to identify the bug from your end. if you need any other info let me know it.

</config>

    </exchange>
</config>

</config>

Thanks in advance for your better support.

I can't see any obvious problems with the configuration you posted. Perhaps the problem lies with your consumer code.

I created a message queue test module which might help you test/debug your message queue module and configuration.
