 * @assertion void ping(

 *      int priority: IMMEDIATE
 * })
 *    Request that the isolate send response on the responsePort.
 * ...
 *    If response cannot be sent to the isolate, then the request is ignored.
 * It is recommended to only use simple values that can be sent to all isolates,
 * like null, booleans, numbers or strings.

 * @description Check that if response cannot be sent to the isolate, then error
