ClientID login error NextJS

Hey, I’m using Auth0 with NextJS but encountering an error after creating an application in the Auth0 console. The error happens when I go to my website and go to the auth0 login page. The error is: " invalid_request : The client with id: (my_client_id) was not found". this is weird because I took the clientId directly from the application after I created it. Also, this used to work before I started specifying clientId and clientSecret in my NextJS app when I initialize Auth0. Any ideas on how to fix? Thanks!
