Select custom field user value as assignee value (Script Runner)

Derek Shortt

I have a workflow post function where a users' manager is the first assignee in the issue. The manager is specified in a custom field. Here is my attempt to implement in scriptrunner: 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.project.Project
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.user.ApplicationUsers
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.event.type.EventDispatchOption

MutableIssue curIssue = issue
CustomField managerField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Manager")
String dUser = managerField.getValue(curIssue)
ApplicationUser cUser = ApplicationUsers.byKey(dUser)
IssueManager issueManager = ComponentAccessor.getIssueManager()
Project curProject = curIssue.getProjectObject()
ApplicationUser projectLead = curProject.getProjectLead()
curIssue.setAssignee(cUser)
issueManager.updateIssue(projectLead, curIssue, EventDispatchOption.ISSUE_UPDATED, false)

However when I run the post function, I get this error:

What am I doing wrong and how can I fix it?

the problem is with the last line. I guess, you pass a null for a parameter. Could you log.error (projectLead) and log.error(curIssue) and have a look in the log, if they are not null?
