I have the same problem, it worked well until today, when suddenly it fails exactly in the same way you describe - I re-created Google API credentials and re-created the n8n credential from scratch but still same result
My intended workflow was to access Google Drive, locate a Google Doc, download and push to Pine Cone Vector. But with the download failing I opted swopping out the Google Doc for PDF. This seems to work fine. But I would still prefer downloading a Google Doc in order to mark up the Doc itself
Hi @Jacques.Grobler
what version of n8n are you using? I just tried using n8n 1.79.1 and I have no issues
could you also try resetting your client secret and see if that helps?
