Laravel 9: Custom login

Question

I am trying to change the default table that laravel 9 uses to authenticate the users. But while I can see that user is authenticanted in the login function of LoginController when I try to redirect to home page as logged in user I get the error

Route [login] not defined.

If the user is logged in why does it try to redirect to login route and not to home

Here is my LoginController.php

public function login(LoginRequest $request)
    { 
        $credentials = $request->getCredentials();
/*
        if(!Auth::validate($credentials)):
            return redirect()->to('login')
                ->withErrors(trans('auth.failed'));
        endif;
*/
        $user = Auth::getProvider()->retrieveByCredentials($credentials);

        if(empty($user)){
            return redirect()->to('login')
                ->withErrors(trans('auth.failed'));
        }

        Auth::login($user);

        //Auth::check() returns true here!

        return $this->authenticated($request, $user);
    }

    /**
     * Handle response after user authenticated
     * 
     * @param Request $request
     * @param Auth $user
     * 
     * @return \Illuminate\Http\Response
     */
    protected function authenticated(Request $request, $user) 
    {
        return redirect()->intended('/home');
    }

and here are my routes in web.php

Route::group(['namespace' => 'App\Http\Controllers'], function()
{   
    
    

    Route::group(['middleware' => ['guest']], function() {
        /**
         * Register Routes
         */
        Route::get('/register', 'RegisterController@show')->name('register.show');
        Route::post('/register', 'RegisterController@register')->name('register.perform');

        /**
         * Login Routes
         */
        Route::get('/login',  'LoginController@show')->name('login.show');
        Route::post('/login', 'LoginController@login')->name('login.perform');
       
        


    });

    Route::group(['middleware' => ['auth']], function() {

        Route::get('/home', 'HomeController@index')->name('home.index');
       

        /**
         * Logout Routes
         */
        Route::get('/logout', 'LogoutController@perform')->name('logout.perform');
    });
});
