無法刪除GCE中的後端服務

Question

我想釋放一些後端服務配額。爲了做到這一點，我相信我首先必須刪除實例組。然而，當我試圖刪除使用該服務實例組，我得到以下信息：

The deletion of the instance group failed. Error: An unknown error has occurred in Compute Engine: "undefined". Error code: "undefined"

我也試圖直接刪除後端服務，但它會涌現一個又一個。另外，我嘗試刪除關聯服務的負載平衡器，但也失敗了。有什麼想法嗎？

正如documentation報道：

"To delete a backend service, you must first make sure that the backend service is not being referenced by any URL maps. If a URL map is currently referencing a backend service, you must delete the URL map to remove the reference."
