Angular Universal不适用于angular pwa

Question

我正在尝试构建具有pwa和通用功能的有角度的应用程序。我面临的问题是，每当我将serviceWorker切换到true时，<app-root></app-root>内部的HTML内容都不会呈现。 有人可以指出我可能会出问题的地方吗？

angular.json

...

            "production": {

                }
              ],

              ],
              "serviceWorker": false,  // setting this to true fails universal rendering
              "ngswConfigPath": "src/ngsw-config.json"

        },
