 * <pre>
 * The response message for a webhook call.
 * This response is validated by the Dialogflow server. If validation fails,
 * an error will be returned in the
 * [QueryResult.diagnostic_info][google.cloud.dialogflow.v2.QueryResult.diagnostic_info]
 * field. Setting JSON fields to an empty value with the wrong type is a common
 * error. To avoid this error:
 * - Use `""` for empty strings
 * - Use `{}` or `null` for empty objects
 * - Use `[]` or `null` for empty arrays
 * For more information, see the
 * [Protocol Buffers Language
