Hopefully this is the right place to ask this. I am trying to use the Google Drive API to access the metadata of all the photos in a folder on my Drive via a project in Google Colab. I am pretty new to APIs and networking in general so I don't really know what I'm doing. I tried to set up the credentials thing on the Google APIs admin site, following this video {https://www.youtube.com/watch?v=zJVCKvXtHtE}. I successfully got a client key and a secret key and added it where I crossed stuff out in the image provided below. I get this error when compiling -- I'm not really sure what it means/how to fix it? I don't know anything about the OAuth2Client library or how the networking stuff works, but all the importing compiles, so I know all the libraries are installed correctly. I'm guessing I didn't set up the credentials correctly. Any tips?
