Unable to Set assignee using ScriptRunner

[Piyush_Annadate]

With the below code - Trying to set the assignee to someone else based on the user (name: Piyush Annadate and userKey as Piyush_Annadate).

This doesn't event assign the issue to other person. What's missing?

Scriptrunner- 5.4.49

JIRA  7.13.1 (Server)

import com.atlassian.jira.component.ComponentAccessor
import org.apache.log4j.Logger
import org.apache.log4j.Level
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.MutableIssue
def log = Logger.getLogger("com.acme.workflows")
log.setLevel(Level.DEBUG)
def issueManager = ComponentAccessor.getIssueManager()
def issueService = ComponentAccessor.getIssueService()
def userManager = ComponentAccessor.getUserManager()
//def issue = issueManager.getIssueObject("HW_TEST-64")

def issue = event.issue
log.info("${issue.projectObject.key}")
log.info("${issue.key}")

def user = ComponentAccessor.getUserManager().getUserByName('Piyush_Annadate')
def validateAssignResult = issueService.validateAssign(user, issue.id, issue.reporterId)
issueService.assign(user, validateAssignResult)

[PD Sheehan · Accepted solution]

The user in issueService.validateAssign and issueService.assign is the user performing the action.

The 3rd argument in validateAssign (String assignee) is the assignee you wish to apply.

Try this instead

import com.atlassian.jira.component.ComponentAccessor
import org.apache.log4j.Logger
import org.apache.log4j.Level
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.MutableIssue
def log = Logger.getLogger("com.acme.workflows")
log.setLevel(Level.DEBUG)
def issueManager = ComponentAccessor.getIssueManager()
def issueService = ComponentAccessor.getIssueService()
def userManager = ComponentAccessor.getUserManager()
//def issue = issueManager.getIssueObject("HW_TEST-64")
def currentUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser

def issue = event.issue
log.info("${issue.projectObject.key}")
log.info("${issue.key}")

def user = ComponentAccessor.getUserManager().getUserByName('pjp')
def validateAssignResult = issueService.validateAssign(currentUser, issue.id, user.name)
if(validateAssignResult.isValid()){
  issueService.assign(currentUser, validateAssignResult)
}
