Setup Laravel Sactum api Login

I'm trying to use Sanctum for a mobile app login and functionality, however, I can't seem to be able to use a controller along with the api routes successfully, this is the original route from the docs

Route::post('/sanctum/token', function (Request $request) {
    $request->validate([
        'scard' => 'required',
        'password' => 'required',
        'device_name' => 'required'
    ]);

    $user = User::where('scard', $request->scard)->first();

    if (! $user || ! Hash::check($request->password, $user->password)) {
        throw ValidationException::withMessages([
            'email' => ['The provided credentials are incorrect.'],
        ]);
    }

    $token = $user->createToken($request->device_name)->plainTextToken;

    $response = [
        'user' => $user,
        'token' => $token
    ];

    return response($response, 201);
});

I wanted to move this into a LoginController for api and turn it into this route

Route::post('/login','API\LoginController@login');

and this method in the API\LoginController.php

public function login(Request $request) {
        $request->validate([
            'scard' => 'required',
            'password' => 'required',
            'device_name' => 'required'
        ]);

        $user = User::where('scard', $request->scard)->first();

        if (! $user || ! Hash::check($request->password, $user->password)) {
            throw ValidationException::withMessages([
                'email' => ['The provided credentials are incorrect.'],
            ]);
        }

        $token = $user->createToken($request->device_name)->plainTextToken;

        $response = [
            'user' => $user,
            'token' => $token
        ];

        return response($response, 201);
    }

The problem is when I try and check this route using Insomnia or Postman, I get these errors:

I'm not sure why this error is happening or how to solve it, it used to say that this LoginController didn't exist but I than deleted it and created it with this command php artisan make:controller API/LoginController --api so now I don't get that missing controller but now I get no message at all
