Trying to populate a multi-user picker custom field with members of a JIRA Group

I'm trying to populate the members of a Jira managed Group into customfield_10031, which is a multi-user picker field.



Here's my attempt to code a JIRA Automation Rule, manually triggered on a single ticket:

"set": {
"customfield_10031": [
{% for member in groups['00000000-bcdd-408d-af9d-f3d7a2cf8421'].members %}
{ "name": "{{ member.key }}" }{% if not loop.last %},{% endif %}
{% endfor %}

The ID is the ID of the group extracted from the URL in Admin / Group management.  This is a Jira/Atlassian group, not another custom field.

When I run this on an issue manually, I just get this error in Automation audit log:

Error while parsing additional fields. Not valid JSON.

I then tried:

"set": {
"customfield_10031": {
"set": [
"name": "{{groups['00000000-bcdd-408d-af9d-f3d7a2cf8421'].members | map(attribute='key') | join('},{\"name\":\"') | replace(' ','')}}"

 Slightly different error: 

No fields or field values to edit for issues (could be due to some field values not existing in a given project).

The field is definitely added to the screen for the issue and request type.


Help would be greatly appreciated!

Hi @Michael Russo 

IIRC the advanced field json you can either use `update` or `fields` 

Can you try updating your JSON to 

"update": {
"customfield_10031": {
"set": [
"name": "{{groups['00000000-bcdd-408d-af9d-f3d7a2cf8421'].members | map(attribute='key') | join('},{\"name\":\"') | replace(' ','')}}"
