Laravel Request Validation: The given data was invalid

PostRequest.php :

{
    "message": "The given data was invalid.",
    "status_code": 500,
    "debug": {
        "line": 117,
        "file": "/var/www/site/vendor/laravel/framework/src/Illuminate/Foundation/Http/FormRequest.php",
        "class": "Illuminate\\Validation\\ValidationException",
        "trace": [
            // ...
        ]
    }
}

I don"t know what went wrong.
