How to add or customize response from laravel validation

Question

I've searched over the internet to find answer for my issue but could not find it. Please see details below.

What response I currently have

{
    "message": "The expected salary field is required.",
    "errors": {
        "expected_salary": [
            "The expected salary field is required."
        ]
    }
}

What I need:

{
    "status": "FAILED",
    "message": "The expected salary field is required.",
    "errors": {
        "expected_salary": [
            "The expected salary field is required."
        ]
    }
}

Validation Rules:

public function rules()
{
    return ['expected_salary' => 'required];
}

By overriding the failedValidation method, you can flexibly customize the validation error response for a specific FormRequest.

<?php

namespace App\Http\Requests;

use Illuminate\Contracts\Validation\Validator;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Http\Exceptions\HttpResponseException;
use Symfony\Component\HttpFoundation\Response;

class FooBarRequest extends FormRequest
{
    // your other code ...

    /**
     * Handle a failed validation attempt.
     *
     * @param  \Illuminate\Contracts\Validation\Validator  $validator
     * @return void
     *
     * @throws \Illuminate\Validation\ValidationException
     */
    protected function failedValidation(Validator $validator)
    {
        throw (new HttpResponseException(response([
            'status' => 'FAILED',
            'message' => $validator->errors()->first(),
            'errors' => $validator->errors()->toArray(),
        ]), Response::HTTP_UNPROCESSABLE_ENTITY));
    }
}

do this

if ($validator->fails()) {
  $error = $validator->errors();
   return response()->json([
            'staatus' => "Failed",
            'error' => $error,
            'success' => false,
            'message'=>'',
        ]); 
}
