How can I get a specific notification scheme object using Scriptrunner?

[Michael Schultz]

How can I get a specific Notification Scheme object for later use in my script?

The script I have below returns: "Cannot invoke method getSchemeObject() on null object" which has to do with my line: 

Scheme archivedScheme = schemeManager.getSchemeObject(schemeId)

What am I doing wrong here? Thanks!

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.project.ProjectCategory
import com.atlassian.jira.notification.NotificationSchemeManager
import com.atlassian.jira.notification.DefaultNotificationSchemeManager
import com.atlassian.jira.scheme.SchemeManager
import com.atlassian.jira.scheme.Scheme

def prList = ComponentAccessor.getProjectManager().getProjectObjects()
def projectManager = ComponentAccessor.getProjectManager()

final SchemeManager schemeManager;

Long schemeId = 12400
Long archivedCategory = 10500
Scheme archivedScheme = schemeManager.getSchemeObject(schemeId)

Get your schemeManager via the ComponentAccessor

def schemeManager = ComponentAccessor.notificationSchemeManager
