  <p>The error looks like this:</p>

  <p>When I look at the mobile.app folder. I see that there is nothing there. No Info.plist. Nothing. Because this is the build folder, it seems like it should be created. Do I have to set it there?</p>
  
  <p>Can sombody give a tip how to solve this? Thanks!</p>
