laravel 应用程序在部署到 AWS 时停止工作

Question

我有一个 laravel 应用程序，它在我的本地机器上运行良好，当我将它部署到 aws 时出现错误。我遇到错误的部分如下。我的应用程序有创建新用户的管理员用户，当创建用户时，会向他们发送一封电子邮件，其中包含一个链接和一个令牌，供他们选择密码。问题是，一旦他们在点击帖子时选择了密码，我就会收到以下错误。

在我的本地机器上，php 版本是 7.2.3 windows。而AWS有7.2.13 elastic beanstalk

Argument 2 passed to Illuminate\Auth\Passwords\PasswordBroker::__construct() must implement interface Illuminate\Contracts\Auth\UserProvider, null given, called in /var/app/current/vendor/laravel/framework/src/Illuminate/Auth/Passwords/PasswordBrokerManager.php on line 75

帖子的相关代码如下：

public function reset(Request $request)
    {
        $request->validate($this->rules(), $this->validationErrorMessages());


        // Here we will attempt to reset the user's password. If it is successful we
        // will update the password on an actual user model and persist it to the
        // database. Otherwise we will parse the error and return the response.

        $response = $this->broker()->reset(
            $this->credentials($request), function ($user, $password) {
                $this->resetPassword($user, $password);
            }
        );

        // If the password was successfully reset, we will redirect the user back to
        // the application's home authenticated view. If there is an error we can
        // redirect them back to where they came from with their error message.
        return $response == Password::PASSWORD_RESET
                    ? $this->sendResetResponse($request, $response)

检查您的配置 auth.php 文件。引发错误的代码是这样的

return new PasswordBroker(
    $this->createTokenRepository($config),
    $this->app['auth']->createUserProvider($config['provider'] ?? null)
);

第二个参数给null，可能是缺少配置？
