[Terraform Support] Error Linking Layer to Function Using Local Variable

AWS SAM CLI support for Terraform is in preview as of today. The team has worked hard to implement a solid minimum viable product (MVP) to get feedback from our community. However, there are a few caveats. Please +1 on individual items to help us prioritize these.

AWS SAM CLI does not currently support linking a Lambda Layer to a Lambda Function using Terraform local variables. Doing this will result in a `LocalVariablesLinkingLimitationException`. Follow this issue for updates on this feature.
