Hi @logistics,
I think I know what the issue is here. This is in a Google Drive share? The main issue stems from the fact that removing an item you do not own from a share is not a “delete” but a “remove”. The delete API we use for deletes to Google Drive is not accepted because of lack of ownership of the file.
Here is a post that goes into it in more detail:
If you want to remove shared items you will need to do so from the Google Drive webclient, for now.
