GitLab - 升級gitlab 版本后項目的webhook等頁面顯示500問題

請注意：GitLab升級請嚴格按照官方文檔版本升級過程進行升級，升級前請備份好數據。
官方地址：https://docs.gitlab.com/ee/update/index.html#upgrade-paths，
若並非按官方文檔升級會出現以下問題，

gitlab 13.3.1升級到14.0.0版本后部分部署過webhook項目的webhook頁面顯示500，其他沒有部署過webhook的項目是正常可以打開的

原因是因為舊的 webhook 與新的 webhook 存在兼容性問題

解決辦法

由於我webhook里的數據可以重新配置，這里只需恢復webhook頁面為正常即可 ，如果需要原數據的話請提前備份原目錄下/etc/gitlab/gitlab-secrets.json文件

進入gitlab數據庫

root@984db48e6398:/# gitlab-rails db
psql (12.6)
Type "help" for help.

查看一下webhook500的項目ID

通過項目ID查出hook的ID

gitlabhq_production=> select id from web_hooks where project_id=65;
 id
----
 35
 40
(2 rows)

可以看到我們這里查出了兩個ID，分別為35和40，我們分辯不出來索性全部刪除

先申請一下項目的令牌tocken

然后退出數據庫連接執行api刪除操作

curl --header "Private-Token: 3hDkYwv-xxxxx8nU" -X DELETE http://git.xxxxx.com/api/v4/projects/65/hooks/35
curl --header "Private-Token: 3hDkYwv-xxxxxu8nU" -X DELETE http://git.xxxxx.com/api/v4/projects/65/hooks/40

然后刷新webhook頁面即可恢復正常
