Laravel 5.1：Kbwebs \ MultiAuth \ Guard'没有方法getAuthIdentifier

Question

我正在运行Laravel 5.1，遇到以下错误。

[2018-08-31 12:38:33] prod.ERROR: Debugbar exception: call_user_func_array() expects parameter 1 to be a valid callback, class 'Kbwebs\MultiAuth\Guard' does not have a method 'getAuthIdentifier' 

我正在尝试使用以下控制器显示用户帐户：

    /**
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
     */
    public function index()
    {

        /** @var User $user */
        $user = Auth::user()->get();
        $transactions = $user->transactions()
            ->with('orders')
            ->where('type', '=', 'mealservice')
            ->whereIn('status', [Transaction::TRANSACTION_STATUS_DONE])
            ->orderBy('created_at', 'DESC')
            ->get();

        if ($transactions) {
            $moments = Moment::get();
            $meals = Meal::get();
        } else {
            $moments = collect();
            $meals = collect();
        }

        return view('website.pages.account.index')
            ->with(['transactions' => $transactions, 'user' => $user, 'userData' => $user->data]);
    }

我能够获得用户->数据。但是一旦触发视图，我就会遇到上述错误。有人有主意吗？
