Resource Api laravel 9 return null - laravel

Question

I have this project that uses Laravel 9 framework and I'm using resource Api method. It worked fine for index and store function but it returns null when it comes update, show ,delete methods. I have my code down below:
My Model:
class Re14 extends Model
{
use HasFactory;
protected $fillable=['re14002'];
}
My Migration:
return new class extends Migration
{
public function up()
{
Schema::create('re14s', function (Blueprint $table) {
$table->id();
$table->string('re14002');
$table->timestamps();
});
}
public function down()
{
Schema::dropIfExists('re14s');
}
};
MY Controller:
class Re14Controller extends Controller
{
public function index()
{
return Re14Resource::collection(Re14::all());
}
public function store(Re14Request $request)
{
$re14=Re14::create($request->validated());
return new Re14Resource($re14);
}
public function show(Re14 $re14)
{
return new Re14Resource($re14);
}
public function update(Re14Request $request, Re14 $re14)
{
$re14->update($request->validated());
return new Re14Resource($re14);
}
public function destroy(Re14 $re14)
{
$re14->delete();
return response("Deleted Successfully!");
}
}
MY Resource
public function toArray($request)
{
return [
'id'=>$this->id,
're14002'=>$this->re14002
];
}
}
My Request
class Re14Request extends FormRequest
{
public function authorize()
{
return true;
}
public function rules()
{
return [
're14002'=>['required','string','unique:re14s,re14002']
];
}
}
MY Route
Route::apiResource('level',Re14Controller::class);
I use Postman to test my Api. It worked fine for index and store but got stack when it comes update, show, delete
{
"data": {
"id": null,
"re14002": null
}
}
