After creating a list on SharePoint Online, I clicked on "Customize forms" under PowerApps in order to create a form with conditional branches. However, once it loads, the following error comes up:

error message

I contacted Microsoft Support, specifically PowerApps however I did not receive much help. Any advice on where the issue lies will be greatly appreciated.


  • I have full control over this site and list
  • I tried creating a test list with just 2 simple columns and it still gave me the same error.
  • I tried another Microsoft account to access it as well. Still the same error.
  • See the logs corresponding to the correlation ID for detailed error. Commented Mar 6, 2019 at 15:37
  • This is what shows up in dev tools - console: HTTP401: DENIED - The requested resource requires user authentication. (XHR)POST - api.powerapps.com/api/invoke

You could check the office 365 version and check if you have enabled PowerApps for the user.

Go to active users->select and click the user->Edit the product licenses.
