@chrisst Hey. It looks like the PR does not fully fix the issue. I have a terraform configuration which provisions a google cloud project and then creates a google_compute_instance_template resource using the dynamically generated project id. I use terraform-google-provider v2.9.0, but unfortunately running terraform plan still fails with google_compute_instance_template.<name>: project: required field is not set error.

$ terraform init -upgrade
...
- Downloading plugin for provider "google" (2.9.0)...
- Downloading plugin for provider "google-beta" (2.9.0)...

$ terraform plan

...
Error: Error refreshing state: 1 error occurred:
