Error 400: Invalid value for field 'resource.distributionPolicy.zones[1].zone': 'zones/us-central1-ai1a' Completed

Some workflows are failing with the following message in the Google Cloud Events tab:

Job gets no longer retryable information Batch Error: code - CODE_GCE_BAD_REQUEST, description - googleapi: Error 400: Invalid value for field 'resource.distributionPolicy.zones[1].zone': 'zones/us-central1-ai1a'. Zone (us-central1-ai1a) must be a valid zone in region us-central1., invalid, already retried 3 times, errors record CODE_GCE_BAD_REQUEST.

This is due to Google Compute Engine's addition of new AI zones, which are not being recognized by Google Batch. The Terra team is in contact with Google Batch about a fix.

Workaround

You can get around this issue by hardcoding these zones in your tasks' runtime blocks:

zones: "us-central1-a us-central1-b us-central1-c us-central1-f"
