get data value from jsonResponse Laravel 8 - laravel-8

Question

I have two controller
the first one has a register method:
public function register(Request $request)
{
$generalTrait = new GeneralTrait;
$user = new User;
$user->email = $request->email;
$user->password = bcrypt($request->password);
$user->type = $request->type;
$user->save();
return $generalTrait->returnData('user',$user);
}
and the second also has register method:
public function register(Request $request)
{
$generalTrait = new GeneralTrait;
$user = (new UserAuthController)->register($request);
$admin = Admin::create([
'admin_name' => $request->admin_name,
//'user_id' => $response->user->user_id,
'user_id' => $user_id
]);
//Admin created, return success response
return $generalTrait->returnSuccessMessage('Admin created successfully');
}
when I try to get data from (JsonResponse) $user I find this error:
ErrorException: Undefined property: Illuminate\Http\JsonResponse::$user
returnDate method in GeneralTrait return:
public function returnData($key, $value, $msg = ""){
return response()->json([
'status' => true,
'errNum' => "5000",
'msg' => $msg,
$key => $value
]);
}
I find same Error when I try to get the status from the $response
How can I fix it?

Answer 1

I fix it by replacing returnData with:
public function returnData($key, $value, $msg = ""){
return [
'status' => true,
'errNum' => "5000",
'msg' => $msg,
$key => $value
];}
so to get user_id from user I said:
'user_id' => ($response["user"])->user_id
I wish I knew what my mistake was, and how I could have fixed it some other way
