Angular 部署问题 - 使用 Dotenv 和 Environment.ts Netlify 环境变量

问：

我在尝试了 dotenv 和 environment.ts 方法后，在我的 Angular 应用程序中访问 Netlify 环境变量时遇到了挑战。

这是我environment.ts文件中的一个片段：

export const environment = {
  production: true,
  apiUrl: 'API_URL',
  hasuraAdminSecret: 'HASURA_ADMIN_SECRET',
};

在 graphql.module.ts 服务文件中，我使用了 dotenv 来访问环境变量：

import { environment } from '../environments/environment';
import 'dotenv/config';

const uri = process.env.API_URL || 'default-api-url';
const adminSecret = process.env.HASURA_ADMIN_SECRET || 'default-admin-secret';

但是，我在这两种方法中都遇到了问题。使用 dotenv 时，存在 polyfill 错误，并且传统的 environment.ts 方法不会显示 Netlify 环境变量的实际值。控制台 .log 输出仅显示变量名称，而不显示值。

我认为Netlify环境变量设置正确。我希望有人能够帮助我解决这个问题。如果您有关于在 Netlify 上的 Angular v16 中使用 dotenv 或 environment.ts 的见解或指导，我们将不胜感激。仅供参考，我正在运行带有以下依赖项的 Apollo 和 GraphQl
