My app is completely blank, cannot run

Anvil Q&A
1

Hello, I need help. I created an attendance app in Anvil, but since yesterday my app is always blank when run. I have tried various ways:

  • Creating a new very simple form (only containing one Label).
  • Pointing StartupForm to that simple form.
  • Checking the browser console (I attached screenshots).
  • Running in incognito mode and different browsers (Chrome, Firefox).
  • Creating a new app with the “Blank App” template (without changing anything), still blank.
  • Fixing indentation in the User_FormAbsensi form code as per forum instructions.

No error appears in the browser console, only messages:

  • “Message not recognised: {fn: ‘ready’}”
  • “Message not recognised: {fn: ‘newAppHeight’, newHeight: …}”

My app: https://4bzdknnkvucgkvot.anvil.app/

What I’ve tried and what’s not working:

Code Sample:

It looks like you’ve now unpublished your app, but if you add a URL again (through the Publish button in the top-right of the Anvil Editor), it should work and you should see your blank startup form with the blue app bar at the top. Please let us know if that isn’t working for you!
