Scriptrunner "Cannot invoke method getCreated() on null object” : scripted field - Last comment

Nilanjana Misra

I have created a scripted field to capture the last comment in a story- Last Comment

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.component.ComponentAccessor

def commentManager = ComponentAccessor.getCommentManager()
def comment = commentManager.getLastComment (issue)
def date = comment.getCreated()
if(comment!=null)

{ return ((date as String) + " " + comment.body + " Author: " + comment.authorFullName) }

return "null";

I am getting below error
2018-02-07 01:05:35,694 ERROR [customfield.GroovyCustomField]: *************************************************************************************
Script field failed on issue: SPD-****, field: Last Comment

Your script should look like this

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.component.ComponentAccessor

def commentManager = ComponentAccessor.getCommentManager()
def comment = commentManager.getLastComment (issue)

if(comment!=null){ 

def date = comment.getCreated()

return ((date as String) + " " + comment.body + " Author: " + comment.authorFullName)

 }

return "null";
