最近，使用 Angular6，我开始在浏览器控制台中观察到描述性极差的堆栈跟踪：

错误错误：“[object Object]”

我怀疑路由模块中有一些错误，所以我正在粘贴我的配置：

const routes = [
  {
    path: 'wordspreview/:id',
    component: WordsPreviewComponent
  },
  {
    path: 'wordspreview',
    component: WordsPreviewComponent
  },
  {
    path: 'search/:query',
    component: SearchResultsComponent
  },
  {
    path: '',
    redirectTo: '/wordspreview',
    pathMatch: 'full'
  }
};

希望有人能提供帮助。

【解决方案1】：

我只是自己发现了这个错误。

无法在其他任何地方搜索它，我将在此处留下解决方案以帮助下一个潜在的受害者：

constructor(private router : Router,
[...]
this.router.navigate([site, id]);

我做错的是导航到错误的site。调试起来很困难，因为它只出现在一些罕见的错误site 值中。
