返回验证错误消息为 JSON

Question

I want to return a failed validation attempt message in JSON from laravel's validator. But upon failed validation I get an 'invalid JSON response' instead. It is not returning any of the custom messages. What am I doing wrong?

Controller

public function uploadArtwork(Request $request) {

$validator = Validator::make(request()->all(), [

        'artwork-title' => 'required|max:240',
        'artwork-description' => 'max:120|nullable',
        'artwork-medium' => 'max:120|nullable',
        'artwork-software' => 'max:120|nullable',
        'artwork-tags' => 'max:120|nullable',
        'files' => 'required',
        'files.*' =>  'required|mimes:jpeg,png,jpg,gif|max:5024',
],
    [   
        'artwork-title.required' => 'Error: Please add title',
        'files.required' => 'choose a photo.',
        'files.image' => 'file should be an image.',
        'files.max' => 'Your photo is too large',
        'files.mimes' => 'We only accept :values.',
   ]
);


 if ($validator->fails()) {
        
 return response()->json($validator->errors());
 
 }

js

 error: function (file, response) {

   // $("#status-message").text(responseText);
   console.log(response);

  }

Actually, above way you didn't send an error response. You are sending a successful response. If you change something like the below will work.

if($validator->fails()){
   return response()->json([
      'status'   => 'error',
      'message'  => $validator->getMessageBag()
   ], 400);
}
