I have 3 separate files for student ,teacher and admin routing and used them in server.js file as general middleware using the use method. when I route with axios .post("http://localhost:5000/student/login", user) in the frontend with react it keeps diverting to admin route. I do not get it? does the middleware I have defined wrong or what? the server console saying TypeError: Cannot read properties of null (reading 'email') at C:\Users\ayex\Desktop\freecodecamp\AASTUweb\server\routes\adminRoutes.js:147:32
