Hello,

This is my script 
import groovy.xml.MarkupBuilder
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.model.ChangeGroup
import com.atlassian.jira.model.ChangeItem
import com.atlassian.jira.issue.history.ChangeItemBean

def commentManager = ComponentAccessor.getCommentManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def priorityChange = changelog?.items.find { it['field'] == 'priority' }
def issue = event.issue
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
if (!priorityChange) {
logger.info("Priority was not updated")
return
}
logger.info("Priority changed from {} to {}", priorityChange.fromString, priorityChange.toString)

Error i received
