We are trying to have users copy files that were shared with them by a service account, but when we use the files.copy method it responds with a 404. The token we have from the user has the drive.file scope.

We could copy directly to users drive after having them give access to the service account, but we want to avoid that because the files will be counting towards the service account quota.

Also, those files are Google native files, (gdocs, gspreadsheet, etc) that can’t be downloaded and re-uploaded.

My question is if I can figure out why when I try to copy to users drive using their own token, that has been shared with them from a service account, Im getting a 404. But also if there’s a different approach I can take.

Thank you
