[网络协议]Grafana Server returned HTTP response code: 422 for URL:XXX

问题场景

通过Grafana HTTP API创建Dashboard，其中传入的JSON内容如下

{
    "id": null,
    "uid": null,
    "title": "Production Overview",
    "tags": [ "templated" ],
    "timezone": "browser",
    "schemaVersion": 16,
    "version": 0,
    "refresh": "25s"
}

结果接口返回报错

Server returned HTTP response code: 422 for URL:
http://XXX:8080/api/dashboards/db

解决

JSON格式不正确，应该为

{
  "dashboard": {
    "id": null,
    "uid": null,
    "title": "Production Overview",
    "tags": [ "templated" ],
    "timezone": "browser",
    "schemaVersion": 16,
    "version": 0,
    "refresh": "25s"
  },
  "folderId": 0,
  "folderUid": "l3KqBxCMz",
  "message": "Made changes to xyz",
  "overwrite": false
}
