根据Laravel Eloquent ORM，$user->Id将返回用户的Id。如果您获取的是null，那么保存时可能会出错。(https://stackoverflow.com/a/21084888/6628079)

保存后尝试打印$user。

更新：如果用户保存成功，在投诉表中添加数据会更好。

protected function create(array $data)
{

    $user = new User;
    $user->name = $data['name'];
    $user->email = $data['email'];
    $user->username = $data['username'];
    $user->password = bcrypt($data['password']);
    $user->role = $data['role'];
    $user->templateURL = "";

    /*$user = User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'username' => $data['username'],
        'password' => bcrypt($data['password']),
        'role' => $data['role'],
        'templateURL' => ""
    ]);*/

    if ($user->save()) {
        if ($data['role'] == 'Verkäufer') {
            $complaintRow = Complaint::create([
                'user_id' => $user->id,
                'complaintCount' => 0
            ]);
        }


        switch ($data['role']) {
            case 'Käufer':
                $user->attachRole(2);
                break;
            case 'Verkäufer':
                $user->attachRole(3);
                break;
            default:
                $user->attachRole(2);
                break;
        }


        return $user;
    } else {
        // Your code if user doesn't save successfully.
    }
}
