core.js:1673 錯誤錯誤：未捕獲（承諾中）：TypeError：無法讀取未定義的屬性“路由”

Question

在實現延遲加載路由模塊時，我在控制台中遇到以下錯誤

core.js:1673 ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'routes' of undefined

如果需要額外的信息，請告訴我。 很長時間以來，我一直試圖找到解決方案，但沒有運氣。

從路由中刪除通配符條目后，上述錯誤被刪除。

以下通配符代碼似乎有什么問題？

{ 路徑：'**'，loadChildren：'../floating-banner/floating-banner.module#FloatingBannerModule' }
