Hi @afreisinger, Thanks for reaching out. This is a known "bug" introduced by the Terraform aws provider >5.55.0 and it seems it won't go away until >6.0.0 as it's part of their aws-go-sdk-v2 migration to fall back on a pseudo region called aws-global. As a temporary work around, please remove any . form your s3 bucket names and all should behave as expected.
