Error: The terraform-provider-google-beta_v3.88.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

make: *** [apply] Error 1

[hazcod]

Seems to be fixed in v3.89.0! However running this undocumented error:

googleapi: Error 400: Cannot specify logging_config or monitoring_config together with logging_service or monitoring_service., badRequest

resource "google_container_cluster" "main_cluster" {

  # use stackdriver GKE for system and workload logs
  logging_service = "logging.googleapis.com/kubernetes"
  logging_config {
    enable_components = ["SYSTEM_COMPONENTS", "WORKLOADS"]
  }

  # use stackdriver GKE for system monitoring
  monitoring_service = "monitoring.googleapis.com/kubernetes"
  monitoring_config {
    enable_components = ["SYSTEM_COMPONENTS"]
  }

...
}

I've als got this error updating to 3.89

[rileykarson]

That issue comes from the API. We don't seem to run into it in our tests where we've set logging_config and logging_service together- I'm not sure why.

You may be able to set logging_service and monitoring_service to "", potentially?

I'm going to lock this issue because it has been closed for 30 days ⏳. This helps our maintainers find and focus on the active issues.
If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.
