Apps Script OAuth2 dropping scopes

[Brad Melluish]

Experimenting with using gcp service accounts to query gemini from a spreadsheet via the OAuth2 library. Using the example from the Google Workspace Installable Triggers guide.

When I run it, the log shows `access: true scopes: undefined`, and I get the following error:

I've tried copying the setScopes function out of the OAuth2 repo and running it on my scope array to make sure I wasn't just doing the input wrong, and it was properly generating a space-delimited list of scopes. Tried passing a space-delimited list instead of an array, still comes back undefined. As best as I've been able to tell, the code is largely the same as whats found in the example I linked above.

The service appears to be successfully getting a token, but something is happening to the scopes. Any insight is appreciated.
