 * Describes the cause of the error with structured details.

 *       "domain": "googleapis.com"
 *       "metadata": {
 *         "resource": "projects/123",
 *         "service": "pubsub.googleapis.com"
 *       }
 *     }
 * This response indicates that the pubsub.googleapis.com API is not enabled.
 * Example of an error that is returned when attempting to create a Spanner
 * instance in a region that is out of stock:
 *     { "reason": "STOCKOUT"
 *       "domain": "spanner.googleapis.com",
 *       "metadata": {
 *         "availableRegions": "us-central1,us-east2"
