Requirement is :

        "labels": {
          "alertname": "[prod] MongoDB Replication Lag - Casper",
          "cluster": "prodcluster",
          "environment": "prod",
          "grafana_folder": "Cluster Casper",
          "ui_frontend": "mongo replication latency"
        },
        "annotations": {
          "__dashboardUid__": "2nrap_l4z",
          "__panelId__": "702"
        },
        "state": "Error",
        "activeAt": "2023-07-17T12:21:20Z",
        "value": ""
      },
      {

Silence : curl -u xxx:xxx --location --request POST 'http://grafana.staged-by-discourse.com/api/alertmanager/grafana/api/v2/silences' --header 'Content-Type: application/json' -d '{"startsAt":"2022-07-27T07:01:01.783Z","endsAt":"2022-07-27T09:01:01.783Z","comment":"created 2022-07-27 15:01","matchers" [{"name":"alertname","value":"[GCP-DEVPLAYGROUND] Virtual Appliances - Service Process stats memory percent - Gcpsensor","isEqual":true,"isRegex":false}]}'

{“message”:“bad request data”,“traceID”:“”}

I am trying to silence using curl command however it does not work, Once I achieve this manual I will program it using python, Please advise .
