typescript - 错误 : Schema must contain uniquely named types but contains multiple types named "n"

Question

我遇到了这个错误，但我不知道如何调试它。当我通过运行 yarn nx serve app 在开发模式下运行它时，它工作正常。当我构建和部署 prod docker 版本时，出现此错误:

    (node:7) UnhandledPromiseRejectionWarning: Error: Schema must contain uniquely named 
    types but contains multiple types named "n".

我查看了所有其他代码库，但没有看到重复数据。而且它不会在开发模式下失败，也只会在生产模式下失败。一段时间以来，我一直在试图弄清楚这一点。非常感谢任何帮助。

Webpack 可能会缩小您在构建应用程序的生产版本时用于生成 GraphQL 模式的类名。

尝试将以下内容添加到您的 Webpack 配置中:

optimization: {
  minimize: false,
}
