角度SSR - ReferenceError：未定义元素

Question

我正在开发一个有角度的7项目。我使用服务器端渲染来允许Facebook爬虫正常工作。到目前为止，我已经开发了一些组件并且还没有遇到任何麻烦。但是现在我遇到了问题，因为我正在使用fullcalendar处理组件...

使用ng s为应用程序提供服务没有任何问题。但是当我尝试使用服务器端渲染npm run build:ssr && npm run serve:ssr构建应用程序时，我现在收到以下错误：npm ERR! code ELIFECYCLE

直到现在我做了一个npm install和npm audit fix，但这没有帮助。我认为这个问题来自于我的app.module.ts或app.server.module.ts中的错误配置，但我无法弄明白。

这里是错误消息的内容：

C:myAppdistserver.js:151900
    var matchesMethod = Element.prototype.matches ||
                        ^
