Description

As AWS launched the Cross Region Pipelines, we don't need to create one pipeline per region or use lambdas to deploy in another region.

We can just simply create one pipeline and S3 buckets in the other regions, so the own pipeline would copy the artifacts and deploy it in other regions.

The unique way to implement that today is using AWS CLI.
Here is the doc: https://docs.aws.amazon.com/codepipeline/latest/userguide/actions-create-cross-region.html

Due to the change of the underlying API implementation for this functionality, the Terraform AWS Provider can unexpectedly crash if a pipeline is manually configured with cross-region support outside Terraform. See also: #7573

It seems like quite a few people are running into crashes as per #7573 due to making changes to a terraform-managed CodePipeline in the AWS Console - I'm assuming that they have updated the Console to automatically set all pipelines as cross-region. I don't know if anyone's actively looking at this or what it would take to fix this, but it looks like it is becoming a little bit more than a nice-to-have!

The change can be as little as someone changing the branch in the source stage, but using the console as it is just needed to push a hotfix or something transitory. If it is done in the console, it breaks Terraform. I would expect Terraform to just put it back if it is not in the code, but not panic and crash.

The functionality for this was merged in via #12549 however GitHub was having issues at the time so closing manually.
