Mail Handler is not adding email into comment section in an exisinting ticket

[Shah Baloch]

Hi,
We would like to use mail handler for Nagios alerts. We would like to create Jira a ticket whenever an alert receive, if an issue exist with same subject then it should add email into comment. I am trying the following script but it is not adding email into comment, it is only creating tickets whenever I send a test email, even I'm sending the same email. Am I missing something?

import com.atlassian.jira.component.ComponentAccessor 
import com.atlassian.jira.service.util.ServiceUtils
import com.atlassian.jira.service.util.handler.MessageUserProcessor 
import com.atlassian.jira.user.ApplicationUser 
import com.atlassian.jira.user.util.UserManager
import com.atlassian.mail.MailUtils 

def userManager = ComponentAccessor.getComponent(UserManager)
def projectManager = ComponentAccessor.getProjectManager() 
def issueFactory = ComponentAccessor.getIssueFactory() 
def messageUserProcessor = ComponentAccessor.getComponent(MessageUserProcessor) 
def subject = message.getSubject() as String 
def issue = ServiceUtils.findIssueObjectInString(subject) 

if (issue) { 
return  
} 

ApplicationUser user = userManager.getUserByName("admin")
ApplicationUser reporter = messageUserProcessor.getAuthorFromSender(message) ?: user
def project = projectManager.getProjectObjByKey("ALERT") 

def issueObject = issueFactory.getIssue() 
issueObject.setProjectObject(project) 
issueObject.setSummary(subject)
issueObject.setDescription(MailUtils.getBody(message)) issueObject.setIssueTypeId(project.issueTypes.find { it.name == "Task" }.id) issueObject.setReporter(reporter) 

messageHandlerContext.createIssue(user, issueObject) 

Here is the email example

Subject: PROBLEM Service Alert: td-application-01/Service Check: PRT is CRITICAL

***** Nagios  Alert *****

Notification Type: PROBLEM

Service: Service Check: PRT
Host: td-application-01
Address: td-application-01
State: CRITICAL
