问题
I'm trying to add a Google Sign In Authentication system to my app, but I keep getting a strange error that I haven't seen anyone get. I'm using EXACTLY the google example code.
I thought it could be some mistake when loading the api, so I checked the async loading and everything seems to be loading properly, but I keep getting this error in the console:
gapi.auth2.ExternallyVisibleError: Invalid cookiePolicy
I searched everywhere for people with the same problem, but I could not find anything similar.
Any ideas?
EDIT: I tried to create a page with ONLY the code of the tutorial, but the error still occurs.

Well, turns out I was trying to test the API by directly acessing my files locally (index.html). The Google Sign In API only works in a running web server. I started a simple node.js server, ran my app trhough this server, and everthing worked just fine.

As already answered by KoJoVe, you need to run inside a web server. If you are using Python 2.7 you might use python -m SimpleHTTPServer 8000 and then use localhost:8000 on your browser
