Get Set for Our Dynamic Web Apps Clementine.js Login Problem

1

I did the steps mentioned here to try Clementine.js to start working on the dynamic web apps.

After that, I ran the app using mongod --smallfiles and then node server.js, and it ran successfully, but when I press the “LOGIN WITH GITHUB” button:

I get this error:

I had the same issue, and I noticed that I forgot to set APP_URL to the “Homepage URL” that I set when registering the app on Github. It’s set to “http://localhost:8080/” if you copy the example from the tutorial. You need to change that to your c9 app url or http://127.0.0.1:8080/ if you’re running it locally.
