Hi,

I want to use the field in body of email alert.  
field name is "cps-aks.paranoid"

I can access the field using the following syntax - ctx.payload.hits.hits.0.\_source.cps-aks.paranoid.

Problem is there is a dot in the field "cps-aks.paranoid", due to which I am getting blank in while using moustache template {{ctx.payload.hits.hits.0.\_source.cps-aks.paranoid}}.

How can I escape the dot in the field name and access the value in email body?

Hey,

there is no way in mustache to access that field as far as I know. However you could use a transform to change the field names from `foo.bar` to `foo-bar`.

See this simplified example

```auto
POST _watcher/watch/_execute
{
  "watch": {
    "trigger": {
      "schedule": {
        "interval": "10h"
      }
    },
    "input": {
      "simple": {
        "foo.foo": "bar"
      }
    },
    "actions": {
      "logme": {
        "transform" : {
          "script" : {
            "lang" : "painless",
            "source" : "ctx.payload['foo-bar']=ctx.payload['foo.foo'] ; return ctx.payload"
          }
        },
        "logging": {
          "text": "{{ctx.payload.foo-bar}}"
        }
      }
    }
  }
}

```

hope this helps!
