Required. Location to make a call. Must refer to a caller's project.

Format: `projects/{project-number-or-id}/locations/{location-id}`.

The `global` location is not supported for batch translation.

Only AutoML Translation models or glossaries within the same region (have
the same location-id) can be used, otherwise an INVALID_ARGUMENT (400)
error is returned.
