Hello everybody!
So, basically I'm trying to get my 'key' value to print it into my mail body, but I'm not being able to do it. Once I get it, I will iterate over the buckets with a "foreach" before the webhook (within the "action" data).
This is the path (it works until I reach the key): {{ctx.payload.aggregations.service.buckets.key}}
I also used this way: {{ctx.payload.aggregations.service.buckets[0].key}}
And this is the "result" output (data is dynamic):
```auto
"result": {
"execution_time": "2022-03-11T13:25:33.552Z",
"execution_duration": 17,

The problem was solved by applying a segment as follows:
{{#ctx._your\_segment\_here_}} {{key}} {{/ctx._your\_segment\_here_}}
