TypeError：无法读取null的属性“ onChildOutletCreated”

Question

我具有以下构建配置，以生成导致以下错误的角度构建。

{
              "fileReplacements": [
   {
    "replace": "src/environments/environment.ts",
    "with": "src/environments/environment.qa.ts"
   }
  ],
  "baseHref": "./",
  "optimization": true,
  "sourceMap": true,
  "namedChunks": false,
  "aot": true,
  "extractLicenses": true,
  "vendorChunk": false,
  "buildOptimizer": false
}

在使用以下功能登录后将用户导航到仪表板时，我遇到了以上错误。 令人讨厌的是，它在本地无法重现，并且在普通浏览器上运行良好，而在隐身模式下，它却失败了，但是，某些用户也在普通浏览器上遇到了此错误，我已经完成了缓存清理的强制重载，仍然无法正常工作，请帮助。

navigateToPage(paramRole) {
    switch (paramRole) {
        case 'verifyEmail': {
            this._router.navigate(['/verify-email']);
            break;
        }
        case 'verifyPhone': {
            this._router.navigate(['/verify-phone']);
            break;
        }
        default: {
            this._router.navigate(['/dashboard']);
        }
    }
}
