Cloud Run Jobs events to trigger Cloud Function with EventArc

I set up a Terraform google_cloudfunctions2_function with the following trigger config:

event_trigger {
    trigger_region        = var.region
    event_type            = "google.cloud.audit.log.v1.written"
    retry_policy          = "RETRY_POLICY_RETRY"
    service_account_email = google_service_account.event.email

    event_filters {
      attribute = "serviceName"
      value     = "run.googleapis.com"
    }

    event_filters {
      attribute = "methodName"
      value     = "/Jobs.RunJob"
    }
...

If I query the Cloud Logs for:

protoPayload.serviceName="run.googleapis.com"
protoPayload.methodName="/Jobs.RunJob"

I can see the events there, but they're not triggering my Cloud Function. Roles are all there:

- roles/eventarc.eventReceiver
- roles/run.invoker
- roles/cloudfunctions.invoker

What am I doing wrong?

What's odd is that this is all v1 in my Audit Logs. The job is created as google_cloud_run_v2_job in Terraform and I explicitly added execution_environment = "EXECUTION_ENVIRONMENT_GEN2", but still v1.

In the Cloud Logs, I can find/filter by those parameters for the events I want to use as a trigger:

I can't believe it is that difficult to trigger something when a Cloud Run Job is done! There should be a simple event already on PubSub just like Cloud Build.

None of the Eventarc methods worked and we subscribed to paid Google Cloud support to get this resolved. The answer is a Log Sink with the following filter:

resource.type = cloud_run_job 
protoPayload.status.message =~ Execution.*.has completed successfully

With PubSub as destination.
