#2231-bot won't send the custom field value to users

I have an HTTP API that successfully populates a custom field called "aqi_result" (I can see the value in Live Chat admin interface).

After the HTTP API element, I added a Text element with #aqi_result# but the bot won't send this to users. It shows nothing at all.

How do I correctly display a custom field value populated by HTTP API in a message to the user?

Please respond ASAP.
