Email alerting

Elastic Stack Elasticsearch
6

I was trying to delete my previous watch and set a new one called countAuth

PUT _xpack/watcher/watch/countAuth
{
  "trigger" : {
    "schedule" : {
      "interval" : "1m"
    }
  },
  "actions" : {
    "email_admin" : {
      "email" : {
        "from" : "Symantec Alerting"
        "to" : "echowu720@gmail.com",
        "subject" : "Error Monitoring Report",
        "priority" : "high"
      }
    }
  }
}

But the response shows

{
  "error": {
    "root_cause": [
      {
        "type": "i_o_exception",
        "reason": "could not parse watch [countAuth]"
      }
    ],
    "type": "i_o_exception",
    "reason": "could not parse watch [countAuth]",
    "caused_by": {
      "type": "json_parse_exception",
      "reason": "Unexpected character ('\"' (code 34)): was expecting comma to separate Object entries\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@1636a0f4; line: 11, column: 10]"
    }
  },
  "status": 500
}
