Basic validation for api user through custom guard without session

I want to create a middleware to do basic validation api users. In middle ware i want to use cutom guard. Here is my code. I have created a middleware named AuthApi.

namespace App\Http\Middleware;

use Closure;

use Illuminate\Contracts\Auth\Factory as Basic;

class ApiAuth { /** * The Guard implementation. * * @var Guard */ protected $auth;

/**
 * Create a new filter instance.
 *
 * @param  Guard  $auth
 * @return void
 */
public function __construct(Basic $basic)
{
    
        $this->auth = $basic;
}

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Closure  $next
 * @return mixed
 */
public function handle($request, Closure $next, $guard='basicAuth')
{
    


        if ($this->auth->guard($guard)->onceBasic()) {

                 return $next($request);
            
        }else{

                $data = ['error' => ['message' => 'Invalid credentials', 'status_code' => 401]];
             return response()->json($data, 404, array(), JSON_PRETTY_PRINT);

        }
        
 
       

}

}

This is the code i used to create a guard in config/auth.php

'basicAuth' => [ 'driver' => 'session', 'provider' => 'users', ],

It does not sent the json error message when user validation is false, so can someone please help me.
