+1-ing. Started running into this problem a few hours ago. I have a Retool app that queries a Google Sheet which had been working as recently as this morning (when I first loaded the app this morning). But it started returning
invalid_client errors, even after deleting and recreating the Sheet resource.
Edit: Just tried with a different Google account + new spreadsheet, but seeing the same issue. Notably I don’t see the dropdown list of sheets in the Retool app anymore and have to use the raw ID option. Once I do that, I still get the invalid client error.
