Conection with Auth0 is not working in my code and same error 404 pops up

Hello Team! so Im experiencing some problems with the routes in my application, there is some problems when Im trying to create the login route and all the times redirect me to the error 404. Even tho I follow the steps on the documentation the error stills pops up.

I dont know if someone had the same problem before and how he solved it. It would be very helpful!

Thank you and have a nice day!
