title: Possible unhandled promise rejection React Native
body: <p>We are trying to send morse code with the use of Agora API and React Native, it works when we are in the start-up channel but as soon as we switch channels it will stop working.
  We use the following method to send morse code and to also hear it on your own device:</p>
  <pre><code>engine.sendStreamMessage(dataStreamId, 'dash');
  beep.setCurrentTime(9.7);
  beep.play();
  </code></pre>
  <p>The datastream ID remains the same when switching channels. We get the following error message:</p>
  <pre><code>    Possible Unhandled Promise Rejection (id: 1):

  <p>It is not clear what argument in what method is invalid? How can we check this?</p>
