title: Storage set JSON : Invalid or unexpected token
body: <p>I am using storage from <code>@ionic/storage</code>and <code>cordova-sqlite-storage</code> to save <code>models</code> in <code>localstorage</code>. In my example:</p>
  
  <pre><code>this.storage.set(this.storageKey, model).then(value =&gt; {
      resolve();
  }).catch(err =&gt; {
      console.log(err);
  });
  </code></pre>
  
  <p>But this error appears:</p>
  
  <blockquote>
    <p>VM1799:1 Uncaught SyntaxError: Invalid or unexpected token</p>
  </blockquote>
  
  <p>I got more informations by clicking on <code>VM1799:1</code>in the Chrome DevTools, and it seems that my models are not well parsed, but I can't understand why :</p>
