Cannot make folder requests:

[kudorgyozo]

Here link it says that you can make folder requests, getting only top level folders by doing:

With a prefix of "" (meaning all files), and a delimiter of "/", you would get:

folder photos/

This doesn't work with your library.

I'm just getting an exception saying that fileId is required. FileId is not required in this case. I checked in postman and it returns top level "folders" correctly.
