Terraform should have handled a failure with the API call due to the region gracefully

Actual Behavior

Provider fails due to error returned stating the operation does not exist in the region.

Hey @thefirstofthe300 👋 Thank you for taking the time to raise this!

We are currently using an emulation service to emulate the C2S regions in a public AWS cloud region to validate our service works

I appreciate you mentioning this; that's really helpful information to have. While I'm not familiar with the offering, I believe I'm understanding correctly that the service you're using is essentially an API-compatible service for mocking deployments to AWS itself, is that correct? And if so, are you able to confirm whether the same behavior occurs when interacting with AWS itself?

While we try not to break compatibility with services like that (you'll find there's a few open issues related to LocalStack, for instance), it's not something that we actively test against. For the sake of transparency, those sorts of issues also generally take more time to be prioritized, with compatibility with the upstream API being more critical to the provider experience.

thefirstofthe300 commented 2 weeks ago

I don't have access to a C2S environment and our partners with access to the environment have given us very little feedback on whether these errors occur so I can't say with any certainty whether the issue occurs in an actual C2S region. That being said, the documentation on the region states in the "How CloudWatch Logs Differs for AWS Top Secret Regions" section that

• Tagging CloudWatch Logs Groups is unsupported.

as well as

The following actions are not supported:
• list-tags-for-resource
• tag-resource
• untag-resource

in the "How CloudWatch Events Differs for AWS Top Secret Regions" leading me to believe that these are still the case and this particular bug is valid.

To explain what happened here, our emulation provider was returning invalid JSON which caused TF to fail instead of use the fallback logic which doesn't set tags. They fixed that bug and everything appears to be hunky-dory now.
