Yes, it looks like flattenAwsLbTargetGroupResource() which was updated in https://github.com/terraform-providers/terraform-provider-aws/pull/7570 is used in both the aws_lb_target_group resource and data source.
The schema for the resource was updated in the PR but not the schema for the data source.

The data source's acceptance tests are failing also:

The fix for this has been merged and will release with version 2.6.0 of the Terraform AWS Provider, early next week.

I am also struggling w/ this error.....

So.. this IS a bug w/ Terraform AWS Provider 2.5.0? This was recently released last week. So.. 2.6.0 is coming out this week to fix?

The fix for this has been released in version 2.6.0 of the Terraform AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
