Set assignee from component lead using script listener

[Alvin]

Hello Community, I need help on scriptrunner, I need to set assignee based on the component's lead. Below is the code that I'm using

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.customfields.option.LazyLoadedOption

// a map with select list option to Component
def componentsMap = [
"BOSS" : "Component1",
"Mashery" : "Component2",
]

def issue = event.issue as MutableIssue

def selectList = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("Affected Service")
def selectListValue = issue.getCustomFieldValue(selectList) as LazyLoadedOption

// there is no value for the select list - therefore do nothing
if (! selectListValue) {
return
}

def componentManager = ComponentAccessor.projectComponentManager
def componentName = componentsMap.get(selectListValue.value)
def component = componentManager.findByComponentName(issue.projectObject.id, componentName)
def userManager = ComponentAccessor.userManager
def components = issue.componentObjects.toList()

if (component) {
componentManager.updateIssueProjectComponents(issue, [component])
}
issue.setAssignee(ComponentAccessor.userManager.getUserByKey(component.lead))

In this code, I have Affected Service as a single select list, if BOSS has been selected, the Component Field will update and set to Component1, but the assignee remains unassigned even if I have default assignee on my component. I know that there's something wrong with my code because I'm a beginner. I need to change assignee everytime component field is changed, that's why I used script listener. Thanks

The following code works; observe

• first of all, it is addCustomFieldValue
• that project picker id has to be converted to string
• user has to be username
• customfields passed should be with their ids

logging to the server is working but to the console after the create is still not working for me
