DriveApp.getFolderByID doesn't work after linking GAS to a Google Cloud Platform Project

[Matt McDonald]

I have a script that has been working for a while now, and within it, it calls DriveApp.getFolderById({folderID}). I wanted to add better logging to my script, so I connected it to a Cloud Platform Project through the UI: 

After I set this script to be connected to a new project, I now receive this error every time I call the script on the line that calls DriveApp.getFolderById({folderID}): 

Any idea how I can fix this without setting up a whole new script?

I'd enable the Google Drive API.

APIs and Services Dashboard

Enable APIS and Service

Search Drive

Enable it

That worked, thank you!
