[GCP] 如何刪除與 Dialogflow 相關的專案 (Unable to delete project)

之前開了一個 GCP 的 project 使用 Dialogflow 實作聊天機器人，而現在沒在使用後想刪除專案卻發生了以下錯誤，紀錄最後如何順利刪除專案的過程

錯誤訊息

Unable to delete project “camel-assistant”

Project “camel-assistant” has one or more liens on it to prevent accidental deletion. To delete the project, remove the liens first then try again.

解決方法

1. 登入 GCP 並開啟 cloud shell

2. 至 project setting 找到對應的 project_id

3. 使用以下指令刪除 project 對應的專案 project_id 與資源 name

   gcloud config set project <your_project_id>
   # Updated property [core/project].
   gcloud alpha resource-manager liens list
   # NAME: p375338413855-ld903cb93-c270-4d41-baaf-2054bac08cd1
   # ORIGIN: You cannot delete this project because it is linked with a Dialogflow agent. Please follow the link to Dialogflow and delete the agent: https://console.dialogflow.com/api-client/#/agent/c70d94b3-7166-4bcd-a501-f654c08fbeb4/
   # REASON: Deletion blocked by Dialogflow.
   gcloud alpha resource-manager liens delete <lien_name>
   # Deleted [liens/p375338413855-ld903cb93-c270-4d41-baaf-2054bac08cd1].
   

4. 可以直接在 project setting 正常刪除專案了 🎉
