Found the error. I was using my route middleware before using the cookie and it was somehow throwing this error. sorry, for not providing the complete code, and thanks for all the reply.

I think you are getting this error because you are not passing the userdata to the login function. I'm not sure but try using below code:

const login = (loginUser, loginPassword) => {
  axios.post('http://localhost:3001/auth/login', {
     username: loginUser,
     password: loginPassword
 }).then(...)
}

You have a route issue! in you route you have:

router.post('/login', loginUser);

And in you test you have:

http://localhost:3000/auth/login

So you need to either add auth in your route definition or remove auth in your axios post

Many things can go wrong. I recommend you to just run the app with a debugger and just check line by line where something is wrong. I see you are using Visual Studio Code. There are many Youtube videos on how to run the app with the debugger.
