      }

Java example

You can extract the custom error code from the ErrorInfo as follows:

try {
  client
    .partners()
    .subscriptions()
    .entitle("partners/partnerId/subscriptions/subscriptionId",
        new GoogleCloudPaymentsResellerSubscriptionV1EntitleSubscriptionRequest())
    .setAccessToken(credential.getAccessToken())
    // It is important to overwrite the parameter: &.xgafv=2.
    // Otherwise, the legacy API mode is used by default, where error details
    // are trimmed off for compatibility.
    .set$Xgafv("2");
    .execute();
} catch (GoogleJsonResponseException e) {
    // process error reason by decoding e.getDetails().
  }
}
