• Please vote on this pull request by adding a 👍 reaction to the original pull request comment to help the community and maintainers prioritize this request
• Please do not leave "+1" or other comments that do not add relevant new information or questions, they generate extra noise for pull request followers and do not help prioritize the request
• The resources and data sources in this provider are generated from the CloudFormation schema, so they can only support the actions that the underlying schema supports. For this reason submitted bugs should be limited to defects in the generation and runtime code of the provider. Customizing behavior of the resource, or noting a gap in behavior are not valid bugs and should be submitted as enhancements to AWS via the CloudFormation Open Coverage Roadmap.

We can still return tfsdk.Provider here. As long as GetMetaSchema is defined on AwsCloudControlApiProvider, it will still fulfill the tfsdk.ProviderWithProviderMeta interface

Unable to figure out how to extract the hcl provider_meta set in test TestAccAWSEC2VPC_metadata. I believe there is something going on here:

https://github.com/hashicorp/terraform-plugin-framework/blob/5c07e076830a6e13f46b356c4a11439382760a85/internal/proto6server/serve.go#L1236-L1239

I'm pretty sure the function applyResourceChange should be able to see the ProviderMeta content from the req *tfprotov6.ApplyResourceChangeRequest but its not populating there, despite the schema getting there.

Once the data is there, i think we have the functionality in place to unpack and add to the new ctx key for user-agent additions
