@SehiiRohoza I have reviewed both logs, and all api calls were GET requests. It was not failing on the provider when it tried to update. When you say `Updating ...`,...

@SehiiRohoza the error I mentioned [here](https://github.com/hashicorp/terraform-provider-google/issues/15643#issuecomment-1696135359) leads me to think this is a temporally or external issue. Unless we can repro, it is hard to see what went to wrong.

@SehiiRohoza cool. Yes, let me know once you have the updates

@shuyama1 any idea what is happening?

@SehiiRohoza is this still an issue with your case? Keep in mind adding dynamic code is beyond what this repo handles. Please share a simple config if your issue can...

@SehiiRohoza reviewed your configs [here](https://github.com/hashicorp/terraform-provider-google/issues/15643#issuecomment-1714379318), the difference appears to be data from between hard-coded and the data source. ``` #group = "https://www.googleapis.com/compute/v1/projects/${local.project_id}/zones/europe-west3-a/networkEndpointGroups/name-${var.environment}-jira-neg" group = data.google_compute_network_endpoint_group.ilb_network_endpoint_group_zonal[0].self_link ``` The hard-coded works but...

@SehiiRohoza what do you see if you hardcode the data source `google_compute_network_endpoint_group` (removing count, etc) and provide **group** with below value in `google_compute_region_backend_service`? ``` group = data.google_compute_network_endpoint_group.ilb_network_endpoint_group_zonal.id ```
