Setting Multi User Field via automation

Question

Hi all,

I know how to set a user via automation. But currently I am struggling to set multi user fields from a group in JIRA.

I have a group in JIRA and a multi user field. 
What I want is when issue transitioned from In Progress to Review, I want the multi user field to be populated with all the users in group via automation. Is this is achievable via JSON or any smart value?

Thank you

Hi @Marc -Devoteam-

I have already tries this but this is what I don't want, because we don't know when a new user will be added or  a user will be deleted.

Drawback for this will we have to monitor the group regularly and update the automation.

I think then your only option is to set in the JSON something like, the following.

Specify the ustom field and ad the individual account id's of each member.

"customfield_11458" : [ { "id":"2s1863211f0z284c45269423" }, { "id":"332212e13z52142111269423" }]

Hi @Marc -Devoteam-

Thanks for the update, unfortunately the JSON throws an error - No fields or field values to edit for issues (could be due to some field values not existing in a given project)
But the field is existing in the project.

Any suggestion?
