This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way.

- Missing resource instance key: Because aws_instance.count has "count" set, its attributes must be accessed on specific instances.

For example, to correlate with indices of a referring resource, use:

aws_instance.count[count.index]
