title: key is AWSPinpoint_MYKEY with options undefined
body: <p>I am getting the following message:</p>
  
  <p>Get item: key is AWSPinpoint_"My_aws_mobile_analytics_app_id" with options undefined</p>
  
  <p>All my info on my aws-export.js are matching my project. </p>
  
  <p>Once I click on the message, the sources from AsyncStorageCache.js:526 says:</p>
  
  <pre><code>/**
   * Get item from cache. It will return null if item doesn’t exist or it has been expired.
   * If you specified callback function in the options,
   * then the function will be executed if no such item in the cache
   * and finally put the return value into cache.
   * Please make sure the callback function will return the value you want to put into the cache.
   * The cache will abort output a warning:
   * If the key is invalid
   * If error happened with AsyncStorage
   *
   * @param {String} key - the key of the item
   * @param {Object} [options] - the options of callback function
   * @return {Promise} - return a promise resolves to be the value of the item
   */
  </code></pre>
  
  <p>I am not sure why I'm getting this error if the key is defined on my my aws-export.js</p>
  
  <p>Thanks for your help</p>
