Expected Behavior

• The google_compute_region_network_endpoint_group resource should be created without a project being defined (the documentation for this resource says that the project field is optional).
• The resource should also be created if a value for the project field is defined.

Actual Behavior

Terraform returns an error:

Error: project: required field is not set
│ 
│   with google_cloud_run_service.cloudrun_neg,
│   on main.tf line 12, in resource "google_cloud_run_service" "cloudrun_neg":
│   12: resource "google_cloud_run_service" "cloudrun_neg" {

This error is produced even when a project ID value is defined in the google_compute_region_network_endpoint_group resource.

Steps to Reproduce

1. terraform apply will produce the error
2. Add project = "PROJECT_ID" line to the google_compute_region_network_endpoint_group resource (with a valid project ID)
3. terraform apply will produce the same error

@andrewmackett did you provide project in the provider block or have the environment variable GOOGLE_PROJECT? It is optional if you have either of one available. Please review below doc that might be helpful.

https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/getting_started#configuring-the-provider

[andrewmackett]

@edwardmedia yes, after hitting this issue I added the project to the google provider block which is a successful work around.

However I believe there's still an issue here because setting a project value on the google_compute_region_network_endpoint_group resource has no effect and it shouldn't be necessary to set the project in the provider if the project is already defined on the resource.

[edwardmedia]

@andrewmackett it works fine with me by adding the project attribute in the resource. Can you provide the exact config (mentioned here) that does not work for you along with the debug log?

[edwardmedia]

@andrewmackett is this still an issue?

[edwardmedia]

@andrewmackett closing assuming it is no longer an issue
