放大 CLI - Angular + Ionic - MFA - AdminQueries API : XMLHttpRequest.handleError [as __zone_symbol__ON_PROPERTYerror]

Question

所以，我使用 Amplify with ionic + angular 并遵循以下 link 和 sublinks，

https://aws-amplify.github.io/docs/js/tutorials/building-ionic-4-apps/

https://aws-amplify.github.io/docs/cli-toolchain/quickstart#administrative-actions

Now, what I want to create is an Admin Panel in my application by which I can create users with MFA enabled for login process (just as it is done via the aws-cognito-console). Therefore, in my form I have provided the email and phone_number as mandatory input fields and for the password I am planning to create an auto-generated one using javascript.

正如我从文档中了解到的那样，这可以通过 AdminQueries API 实现，并且在使用 amplify cli 初始化我的项目时，我进行了所需的配置。结果，我确实在放大后端文件夹中准备好了样板代码，如下面的屏幕所示，

不幸的是，样板代码没有实现 AdminCreateUser 方法，即

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CognitoIdentityServiceProvider.html#adminCreateUser-property

因此，我自己在 cognitoActions.js 中创建了这个方法，并且在 app.js 中实现了相同的路由，做了一些 CORS 设置最后做了一个 amplify push

但是当我尝试从 amplify-angular 方法访问这个 api 方法时，它给了我以下错误（我已将错误粘贴在屏幕截图下方）

这就是我在请求、响应中的全部内容 headers,

----更新 1 -----

我已将以下内容添加到我的 polyfills.js、

(window as any).global = window;
(window as any).process = {
  env: { DEBUG: undefined },
};

这是给我的 index.html

<script>
  if (global === undefined) {
    var global = window;
  }
</script>

所以我做了一个放大删除，即从我的 angular 2 项目中删除放大并移动到 nodejs aws sdk，在我的无服务器后端代码中以及现有的 lambda 函数现在我有更多使用以下管理查询 API、

创建、删除和列出用户的 lambda

https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_AddCustomAttributes.html

Amplify 的文档仍然损坏，因此，我建议使用上面 link 中提到的更强大的 API / SDK。
