Automation : set custom field with assignee

Hi all,

I created a custom field called "Developer(s)" (type of field: User Picker (multiple user)) and I would like to automate an action when I make a transition to a particular state.

I would like to trigger an action to *set* to this custom field the name of the assignee. Is this possible? Ideally, even better, I would like to *add* to this custom field the name of the assignee if there is already another name (but it may be too much to ask...).

I tried many things like what is proposed in the following thread, but I cannot get it to work, maybe this does not apply to custom fields?

For example:

    "fields": {
        "engineer": { "id": "{{assignee.accountId}}" }


    "update": {
        "Developer(s)": [{
            "set": {{initiator.accountId.asJsonObject("id")}}

Any ideas? :)

Hi @Jérôme Coupé 

Just in case you still need this answered - it is possible without JSON!

For the Action Edit Issue, set the parameters as follows...

  • Field = <Custom Field>
    • Select the 3-dots icon next to the value field, and select COPY
    • Press the button which replaces the value field, and set the values to...
      • Issue to copy value from = Trigger Issue
      • Field to copy value from = Assignee
      • Add to existing values = Checked

Let us know if this works for you!
