Is there an existing issue for this?
- I have searched the existing issues
Current Behavior
Starting version 4.1.0, subscribing to a topic from a different region fails with the following:
An error occurred (NotFound) when calling the Subscribe operation: Topic does not exist
I think the bug has been introduced by #12175, with the intention of raising the error for legit cases.
The code might be pretty self explanatory of the bug. If I understand correctly, here we should check the store corresponding to the region of the topic ARN we want to subscribe to, not the store of the region we are subscribing from.
Expected Behavior
Subscribing to a topic from a different region succeeds.
