I am able to create the db using aws cli with the same parameters but still no dice on terraform

I believe @ewbankkit's changes in #33790 addresses this.

[rymaclen]

I am still having this issue after upgrading to the AWS 5.21.0 version. The behavior has not changed

Terraform v1.6.0
on darwin_arm64

• provider registry.terraform.io/hashicorp/aws v5.21.0
• provider registry.terraform.io/hashicorp/random v3.5.1

@rymaclen It looks like DocumentDB is not available in us-west-1: https://docs.aws.amazon.com/documentdb/latest/developerguide/what-is.html.

[rymaclen]

Thank you! That would be why.
