У меня есть следующий код. Предполагается отправить данные формы title, tag и description на контроллер для загрузки. Но я продолжаю получать эту ошибку.
Ошибка:

А вот и MyController :

if (!$title == null) {
return redirect()->back()->withErrors(['Title Already Exists', 'Title already exists']);
return response()->json(["message" => "Failed","reason" => "Title Already Exists"]);
}
$post = Post::create([
'title' => $request->input('title'),
'body' => $request->input('body'),
'description' => $request->input('description'),
'type' => $request->input('type'),
'user_id' => auth()->id(),
'published_at' => $request->has('draft') ? null : \Carbon\Carbon::now()
]);
}
StorePostRequest.php
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Support\Facades\Auth;
class StorePostRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
