Watcher action returns some payload, but not others

Hi ,

I have the following watcher action :

"send_email": {
              "transform": {
                "script": {
              "source": 
              """
              def documents = ctx.payload.hits.hits.stream()
            .map(hit -> [
              "time": hit._source['@timestamp'],
              "source.user": hit._source.EventData.SubjectUserName,
              "destination.user": hit._source.EventData.TargetUserName,
              "message": hit._source.System.Keywords
            ])
            .collect(Collectors.toList());
            return documents[0]; 
              """
            }
              },
              "email" : { 
                "to" : "<<redacted>>", 
                "subject" : "Watcher Notification", 
                "body" : "On {{ctx.payload.time}}, {{ctx.payload.source.user}} is making changes to {{ctx.payload.destination.user}} with message  {{ctx.payload.message}}"
              }
            }

Upon watch execution, I can see that the transform returns expected payload. however, on the action section, some payload are returned while others are not.

transform result :

"transform" : {
            "type" : "script",
            "status" : "success",
            "payload" : {
              "time" : "2020-05-29T06:51:54.969Z",
              "source.user" : "<redacted>",
              "destination.user" : "<redacted>",
              "message" : "Audit Success"
            }
          },

action result. :

"email" : {
            "account" : "office365",
            "message" : {
              "id" : "send_email_modify-ad_eedaa620-e8e6-4984-b33e-9b6fc21b0113-2020-06-09T14:37:47.69609Z",
              "from" : "<redacted>",
              "sent_date" : "2020-06-09T14:37:47.714366Z",
              "to" : [
                "<redacted>"
              ],
              "subject" : "Watcher Notification",
              "body" : {
                "text" : "On 2020-05-29T06:51:54.969Z,  is making changes to  with message  Audit Success"
              }
            }
          }

The time and message field are returned correctly, while source.user and destination.user are just blanks. Strangely enough, putting just {{ctx.payload}} returned all entries.

Did i miss something obvious?

TIA

Try not to use dots within field names. Try destination_user and see if htat solves the problem.

yup, a friend figured that out as well
