如何通过Grafana API创建PagerDuty联系点？报错排查

尝试通过Grafana API创建PagerDuty联系点，参考官方文档将YAML配置转为JSON发起请求，收到错误：

{"message":"invalid object specification: type should not be an empty string","traceID":"00000000000000000000000000000000"}

使用的API请求代码（已替换虚拟密钥）：

curl -X POST --insecure -H "Authorization: Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" -H "Content-Type: application/json" -d '{
  "contactPoints": [
    {
      "orgId": 1,
      "name": "test1",
      "receivers": [
        {
          "uid": "test1",
          "type": "pagerduty",
          "settings": {
            "integrationKey": "XXXXXXXXXXXXXXXX",
            "severity": "critical",
            "class": "ping failure",
            "component": "Grafana",
            "group": "app-stack",
            "summary": "{{ `{{ template \"default.message\" . }}` }}"
          }
        }
      ]
    }
  ]
},
  "overwrite": false
}' http://XXXXXXXXXXXXXXXX.us-east-2.elb.amazonaws.com/api/v1/provisioning/contact-points

请求的JSON格式存在语法错误：contactPoints数组的闭合大括号后多写了一个}和逗号，导致整个JSON结构被破坏。Grafana无法正确解析请求体，进而误判type字段为空。

修正JSON结构，将contactPoints和overwrite放在同一个顶层对象内，正确的curl命令如下：

curl -X POST --insecure -H "Authorization: Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" -H "Content-Type: application/json" -d '{
  "contactPoints": [
    {
      "orgId": 1,
      "name": "test1",
      "receivers": [
        {
          "uid": "test1",
          "type": "pagerduty",
          "settings": {
            "integrationKey": "XXXXXXXXXXXXXXXX",
            "severity": "critical",
            "class": "ping failure",
            "component": "Grafana",
            "group": "app-stack",
            "summary": "{{ `{{ template \"default.message\" . }}` }}"
          }
        }
      ]
    }
  ],
  "overwrite": false
}' http://XXXXXXXXXXXXXXXX.us-east-2.elb.amazonaws.com/api/v1/provisioning/contact-points

• 确认Authorization的Bearer令牌拥有Grafana的编辑权限
• 确认PagerDuty的集成密钥有效且对应正确的服务
• 检查Grafana版本是否支持该API端点（v9+版本支持/api/v1/provisioning/contact-points）
