GitLab - 升级gitlab 版本后项目的webhook等页面显示500问题

请注意：GitLab升级请严格按照官方文档版本升级过程进行升级，升级前请备份好数据。
官方地址：https://docs.gitlab.com/ee/update/index.html#upgrade-paths，
若并非按官方文档升级会出现以下问题，

gitlab 13.3.1升级到14.0.0版本后部分部署过webhook项目的webhook页面显示500，其他没有部署过webhook的项目是正常可以打开的

原因是因为旧的 webhook 与新的 webhook 存在兼容性问题

解决办法

由于我webhook里的数据可以重新配置，这里只需恢复webhook页面为正常即可 ，如果需要原数据的话请提前备份原目录下/etc/gitlab/gitlab-secrets.json文件

进入gitlab数据库

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

查看一下webhook500的项目ID

通过项目ID查出hook的ID

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

可以看到我们这里查出了两个ID，分别为35和40，我们分辩不出来索性全部删除

先申请一下项目的令牌tocken

然后退出数据库连接执行api删除操作

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页面即可恢复正常
