[bflad]

Thank you so much for reporting this, @peterpakos! This may be due to changes related to the CloudFront Cache Key and Origin Request Policies since the forwarded values within the cache behaviors can now be controlled with separate CloudFront components and those simply referenced in the cache behavior. Terraform AWS Provider support for that new functionality can be tracked in #14373.

This should be fixed by #14993, which will be merged shortly and released tomorrow with version 3.5.0 of the Terraform AWS Provider. 👍
