title: Forge design automation app stack at "workitem started:
body: <p>I am using learn.forge.designautomation-master sample code. Using VS 2019, ngrok as described in forge tutorial.So far did not do any mistake knowingly. Please see the screen shot. The app is stack as the screen shot. </p>
  
  <p>What could be the reason ? I have my own app bundle and similar app, having same trouble. So I thought I should try with forgesample, and bang same error here. I guess I am doing some common mistake, as a beginner. Please give me some clue, what could cause it. </p>
