Metricbeat GCP module cloudsql not working

I'm trying to get Cloud SQL metrics with this module config without success:

- module: gcp
  metricsets:
    - metrics
  region: "us-"
  project_id: "my-project"
  credentials_file_path: "/usr/share/metricbeat/config/pkey.json"
  period: 300s
  metrics:
    - aligner: ALIGN_NONE
      service: cloudsql
      metric_types:
        - "database/cpu/utilization"

"message": "Could not read time series value: cloudsql.googleapis.com/database/cpu/utilization: rpc error: code = InvalidArgument desc = The supplied filter does not specify a valid combination of metric and monitored resource descriptors. The query will not return any time series." },

cloudsql.googleapis.com/database/cpu/utilization is the same value I see if I go to the Metrics explorer so I'm not sure what's going on.

The solution was to remove the region property as Cloud SQL API doesnt expose that and the filter that metricbeat build breaks.

I opened an issue : https://github.com/elastic/beats/issues/32906

Working configuration:

- module: gcp
  metricsets:
    - metrics
  project_id: "my-project"
  credentials_file_path: "/usr/share/metricbeat/config/pkey.json"
  period: 300s
  metrics:
    - service: cloudsql
      metric_types:
        - "database/cpu/utilization"
