Using Liquid in the options keys of agents

[gms8994]

First off, thank you for Huginn. I've tried using it for several years and never had a good use case for it, but it's been on my radar for a long time. The fact that it's still here is a testament to the product and to the team!

I have an EventFormattingAgent that's taking input from a WebsiteAgent. I'd like the resulting output of the EventFormattingAgent to have keys that are based on an item in the input - in short, I'm trying to use EventFormattingAgent to format the events such that they could be put in to prometheus. However, Huginn doesn't seem to apply liquid templating to the keys of the options, only to the values. When I dry run the agent, I get the unmodified version of the keys as shown below.

Am I doing something wrong? Is there a better way to get what I want?

EventFormattingAgent options

{
  "instructions": {
    "action{{ prom_gauge_group_start }}{{gauge}}{{ prom_gauge_group_end }}": "{{ action }}",
    "bankfull{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "{{ bankfull }}",
    "flood{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "{{ flood }}",
    "moderate{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "{{ moderate }}",
    "major{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "{{ major }}",
    "record{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "{{ record }}",
    "forecast{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "{{ forecast }}"
  },
  "mode": "clean"
}

Incoming data

{
  "action": "...",
  "bankfull": "...",
  "flood": "...",
  "moderate": "...",
  "major": "...",
  "record": "...",
  "forecast": "...",
  "gauge": "...",
  "prom_gauge_group_start": "...",
  "prom_gauge_group_end": "..."
}

Dry run results

[
  {
    "action{{ prom_gauge_group_start }}{{gauge}}{{ prom_gauge_group_end }}": "21",
    "bankfull{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "20",
    "flood{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "23",
    "moderate{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "30",
    "major{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "38",
    "record{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "5215",
    "forecast{% raw %}{{gauge=\"{% endraw %}{{gauge}}{% raw %}}}{%endraw%}": "1250"
  }
