Thank you. I tried this but am getting:

InvalidOperationException: Entity cannot have auto-forwarding policy to itself

I'm running in to this error as well. Do I need to be using a premium instance of ASB?

No, you just need to make sure you don't have a receive endpoint with the same name as the topic. Pretty common mistake. Specifying custom entity names is the most common path to these type of errors.

No, you just need to make sure you don't have a receive endpoint with the same name as the topic.

This was my mistake ^

Thanks, guys. This was my problem. It's starting to come together, now!
