我正在尝试让我的 Flutter Web 应用程序与 Firebase Google Auth 一起使用。一切都在本地工作，但在生产服务器（托管在 Firebase 上）上，我只得到以下无用的堆栈跟踪：

这是一个全新的项目，具有最新的 Flutter / Firebase 依赖项。我的索引 html 如下所示：
...
<head>
<meta name="google-signin-client_id" content="myActualId.apps.googleusercontent.com">
</head>
<body>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-auth.js"></script>
我还在“授权域”下的 Firebase 控制台“登录方法”中添加了我正在使用的域。我可以做些什么来调试这个问题？
