Missing authentication token for REST error

Hello! I'm getting a missing authentication error and was wondering if anyone can help me.
I'm using version 6.1.1

My code without credentials:

PUT _xpack/watcher/watch/cluster_yellow3
{
  "trigger": {
    "schedule": {
      "interval": "10s"
    }
  },
  "input": {
    "http": {
      "request": {
        "scheme": "http",
        "host": "localhost",
        "port": 9200,
        "method": "GET",
        "path": "/_cluster/health",
        "params": {},
        "headers": {}
      }
    }
  },
  "condition": {
    "compare": {
      "ctx.payload.status": {
        "eq": "yellow"
      }
    }
  },
  "actions": {
    "notify_pager" : {
      "webhook" : {
        "method" : "GET",
        "host" : "ip",
        "port" : 8030,
        "path" : "/TSSparam.do"
      }
    }
  }
}

Error code (result of my simulation):

"error": {
  "root_cause": [
    {
      "type": "security_exception",
      "reason": "missing authentication token for REST request [/_cluster/health?]",
      "header": {
    "WWW-Authenticate": "Basic realm=\"security\" charset=\"UTF-8\""
      }
    }
  ],

Hello @Miho,

Your /_cluster/health HTTP query is missing authn info. This here is an old answer about the same error.
