How to assign user to custom people field

[Julez]

{
   "fields": {
       "QC": {{assignee.key.asJsonObjectArray("id")}}
   }
}

is what I currently have and thanks to the increbibly lacking documentation I can't figure out how to store the current assignee in a custom people field.

This is a People field added to all issue types which isn't Reporter or Assignee and it has no default users and the Tickbox for `Restrict to a single user` is not turned on.

Please help

Hi @Julez 

The assignee has the "accountId" attribute and the user field set is looking for "id".  So a work-around is to grab the field that is there, convert to the array, and then substitute the attribute name.  Perhaps like this:

{{assignee.asJsonObjectArray("accountId").replaceAll("accountId", "id")}}

Kind regards,
Bill

Thanks Bill

I still get the very helpful

Error while parsing additional fields. Not valid JSON.

when using that code.

The only code I have in the advanced field is

{
  "fields": {
    "QC": {{assignee.asJsonObjectArray("accountId").replaceAll("accountId", "id")}}
  }
}

Sorry, I was clearly thinking of something else when I first answered...assignee is not a list (and so does not use array functions). This is better:

{
  "fields": {
    "QC": { "id": "{{issue.assignee.accountId}}" }
  }
}

Thanks for your help Bill. 

The correct syntax turned out to be:

{
  "fields": {
    "QC": [{ "id": "{{issue.assignee.accountId}}" }]
  }
}

I can't believe how incredibly ill-documented these advanced features are. We just need a wiki.

I submitted a suggestion to make the smart value/automation documentation much more like the one for the REST APIs, with everything on one page, context indicators (by product: Cloud, Server/DataCenter, JSM, Admin), examples that can be downloaded and imported, and links to KB articles for known gotchas.
