Updated way to set Description field using ADF in an Automation rule

[Rebekka Heilmann (viadee)]

It used to be possible to set the Description field in an Automation via the "more options" using JSON and ADF, see Solved: Updating description field using REST API and Atla... for reference.

I just tried it out again and am now getting an Error message stating

(Operation value must be a string (description))

Pretty sure the solution provided in the other thread worked at some point as I used that before. 

My workaround now is to recreate the formatting via Markdown using the "normal" set Field option (no JSON). But my colleague needs a numbered header column which I cannot set via Markdown.

Any idea why ADF isn't working within the JSON anymore?

I tried updating description using below and it worked fine. Can you share what are your rule in Additional fields

{
"fields": {
"description": "Updating description using automation {{issue.key}}."
}
}
