Hi @Jaina Chavda -- Welcome to the Atlassian Community!

Adding to the suggestion from Mike, the JSON expression is not needed.

Instead the field may be set directly by selecting it from the dropdown list entering the smart value for the user who triggered the rule: {{initiator.accountId}}

When the value appears below the field, select it to use for the edit.

Kind regards,
Bill

OK, I guess you have to use JSON and {{initiator.displayName}} then.

Please get the ID of the custom field:

Please try it with this JSON in More options - Additional fields:

{
  "fields": {
    "customfield_12346": {
      "id": "{{initiator.accountId}}"
    }
  }
}

* Unselect QA tester in Choose fields ...
* Enter your Custom field ID

I do not want to change assignee but rather a new custom field called QA tester ( user single select)

and right now the "user who triggered the event" option is not showing
