Error while running an unattended process in Apps


I made an easy app to search a product in multiple retail site to compare prices.

When I run the process in attended mode it works, but when I try with the process unattended I keep getting this Error.

Does anyone know how to fix this problem?


any update on this?

“Ok” - Possibly the least descriptive error message of all time. I’ve got an educated guess about what might be going on here. Can you double check that you user has all of the required permissions for running unattended processes in apps? I think you might be missing view/create webhooks.
