google cloud platform – GCP Storage Transfer Service is not publishing error count metric for a transfer job

I’m using Google Cloud Storage Transfer Service to transfer data between Cloud Storage buckets via agentless transfer, and I’ve noticed that the error count metric (storage_transfer_job.error_count) is not being published for my transfer job. Even when the job encounters failures (e.g., due to missing objects or permission issues), the metric does not reflect any errors. Other related metrics, such as storage_transfer_job.found_bytes_count, are being updated correctly. This issue makes it difficult to monitor and alert on transfer failures programmatically.

I have verified that Cloud Monitoring is enabled and that other transfer-related metrics are being updated. However, despite these failures being logged, storage_transfer_job.error_count remains at zero. I expected this metric to increment when errors occur, allowing me to monitor and alert on failed transfers, but that is not happening. Is there any additional configuration required, or could this be a bug?
