Is there I can send first message using request ?

Answer

-For custom message

 Laravel Documents customizing-the-error-messages

-For return single error message

    //In Request
    use IlluminateContractsValidationValidator;
    use IlluminateHttpExceptionsHttpResponseException;
    
    protected function failedValidation(Validator $validator)
    {
        throw new HttpResponseException(response()->json([
            'success' => false,
            'message' =>$validator->errors()->first(),
            'data' => null,
        ], 422));
    }
