| `Response.message`  | object | The successful protobuf message, serialized to JSON. Will be `null` if `status !== grpc.StatusOK`.                                       |
| `Response.headers`  | object | Key-value pairs representing all the metadata headers returned by the gRPC server.                                                       |
| `Response.trailers` | object | Key-value pairs representing all the metadata trailers returned by the gRPC server.                                                      |
| `Response.error`    | object | If `status !== grpc.StatusOK` then the error protobuf message, serialized to JSON; otherwise `null`.                                     |

```javascript
import grpc from 'k6/net/grpc';
import { check, sleep } from 'k6';

const client = new grpc.Client();
client.load(null, 'quickpizza.proto');

export default () => {
  client.connect('grpc-quickpizza.grafana.com:443', {
    // plaintext: false
  });

  const data = { ingredients: ['Cheese'], dough: 'Thick' };
  const response = client.invoke('quickpizza.GRPC/RatePizza', data);

  check(response, {
    'status is OK': (r) => r && r.status === grpc.StatusOK,
  });

  client.close();
  sleep(1);
};
