Why

The principal might be wrong. https://aws.amazon.com/premiumsupport/knowledge-center/s3-invalid-principal-in-policy-error/

If you grant another account, but that account is not enable this new opt-in region (e.g. HongKong), the error shows. For example, the account 325227931631 doesn't enable HongKong region.
