[This is a documenting issue.]

Immediately after a role is created, AWS sometimes returns a unique ID (e.g., AROAQ7SSZBKHRKPWRZUN6) in the ARN field. This can create problems with drift detection and problems like seen in #8905. The problem appears to be random and may depend on how busy AWS is currently.

The AWS provider should not ever include a unique ID in aws_iam_role.arn regardless what AWS returns.

Affected Resource(s)

• aws_iam_role

Expected Behavior

ARN attribute should always be an actual ARN (e.g., arn:aws:iam::12345678901:role/tf-acc-test-7531775986226331375-mercedes).

Actual Behavior

Occassionally (rarely), aws_iam_role.arn is a unique ID (e.g., AROAQ7SSZBKHRKPWRZUN6).

Steps to Reproduce

1. terraform apply
2. Wait for planets to align
3. Preferably try this when AWS is really busy (maybe during re:invent?)
4. See strange occurences
