Required. Project or location to make a call. Must refer to a caller's
project.

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

For global calls, use `projects/{project-number-or-id}/locations/global` or
`projects/{project-number-or-id}`.

Non-global location is required for AutoML models.

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