file.setOwner(new_owner) -> Action not allowed

[Mirri360]

I'm trying to adapt this code for my use as I have several hundred files that I need to transfer ownership on. I have adapted the search and listed the names to verify that I have the correct files in my files list. However, when I tried adding either of the addEditor or the setOwner commands, I got the "Action not allowed" error message. I changed the manifest as directed by the documentation by adding the following code to the manifest. I don't intend to publish. Is there something else I need to do to make those commands work?
"oauthScopes": [ "https://www.googleapis.com/auth/drive" ]

Are these in a Team Drive? That could be an issue. Does the account that's running the script have actual access to those files? Ideally, you'd want to run the script as the original owner in order to make someone else the owner.

Mine is a personal Google account and I'm logged in and also the owner of all the files. The google account I want to transfer ownership to is already editor on all the files. Is it possible that I can't do it because they aren't Docs or spreadsheets...? They are almost all movies.

Not sure. Honestly, I haven't tested this script in multiple scenarios. This is definitely more of an "I found this useful, so you might, too" projects than "This is a publicly released fully tested project I'm supporting" projects.

No problem. I thought you might have known something else that I needed to do to make it work. Anyway, I modified my script to change the ownership of a Google Doc file and that worked. I suspect, we are just not allowed to change ownership of a movie file (or any other non-Google file). Very frustrating.
