Exception: You do not have permission to access the requeste

Hello, thank you to the creator and the message board admins.  I have successfully manually run the app but when I set up the hourly timer I get this result: Exception: You do not have permission to access the requested documentnat refreshVideos(Code:111:43)

I have searched the GITHUB & this message board but could not find a solution to this problem. Thanks for all you have done and thanks in advance for any guidance you can provide.
