Hi @ipmb 👋 Thank you for reporting this and sorry you are running into trouble here. The error code and symptoms indicate that this is related to #11706 and #11682 (which is a regression where the error messaging is not correctly surfaced by the AWS Go SDK) so to consolidate discussions and efforts, I'm going to close this issue in preference of the existing one. The good news is that this should be resolved via AWS Go SDK update today and Terraform AWS Provider release tomorrow. 👍
