I had a problem with mongo that i didnt know how to solve and i cloned and set up the local app again.When i went to localhost and i clicked on sign in , it redirected me to
https://stuff/authorize?response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fauth0%2Fcallback&scope=openid%20email&client_id=stuff.

I didnt do anything different from when i first set up my local app other than updating my fork.
I am currently working on an open source assignment in my university in which i chose freecodecamp to contribute to and it would really help me if anybody knew what is wrong or how can i bypass it so i can work locally.Because of this problem i am facing i cant see the challenges and cant see if i make any progress or not while i am working on adding challenges.
Thank you all in advance.
