Flutterflow 包 plaid_flutter：^3.1.4 在自定义操作中使用正确的 LinkToken 初始化 PlaidLink 时会引发错误。我错过了什么？

Question

我能够从 Plaid 成功获取链接令牌。但是，当我将其传递给应用程序（在桌面和移动浏览器的 Flutterflow 测试模式下尝试）并尝试初始化格子链接时，它失败并出现以下错误。

出于安全目的，我屏蔽了链接令牌，但我确认链接令牌是有效的。

打开 PlaidLink 功能失败。

有人之前在 Flutterflow 中尝试过这个包并阐明我可能缺少的内容吗？

自定义操作代码：

import 'package:plaid_flutter/plaid_flutter.dart';

Future initPlaidLink() async {
  // Add your function code here!
  print('Initializing Plaid Link');

  LinkConfiguration configuration = LinkTokenConfiguration(
    token: "link-sandbox-xxxxxxxxxxxxxxxxxxxxx",
  );

  PlaidLink.open(configuration: configuration);
}

错误：

你能确认你有吗？

<script src="https://cdn.plaid.com/link/v2/stable/link-initialize.js"></script>

在index.html文件中？根据 https://github.com/jorgefspereira/plaid_flutter/issues/111，没有该行可能会导致此问题。
