G Suite Drive API: Why can't I get the permissions of a specific file?

Question

I am consuming data from the G Suite Drive API and I am getting the following error:

[2020-05-09 05:42:33,626: INFO/ForkPoolWorker-1] URL being requested: GET https://www.googleapis.com/drive/v3/files/<FILE_ID>/permissions?fields=%2A&alt=json
[2020-05-09 05:42:34,089: WARNING/ForkPoolWorker-1] Encountered 403 Forbidden with reason "insufficientFilePermissions"
[2020-05-09 05:42:34,089: WARNING/ForkPoolWorker-1] drive#permission: HTTP error (code 403): The user does not have sufficient permissions for this file.

The file causing the trouble is a JPEG. I have both the file ID and the file name.

The situation is as follows:

• When looking for the file using the Drive Files API and providing the file ID a 200 HTTP response is returned.
• When looking for the file permissions using the Drive Permissions API, a 403 HTTP error is raised.
• When looking for the file using the Drive search bar and providing the file name, nothing is found.

Can anyone shed light on this?

Thank you for your time.

If your permissions allow you to use Files: get but not Permissions: list, you have only View Access to a file

You need to be an editor or owner to use Permissions:list
