Nullpointer exception is thrown while creating a subtask

Question

Hi,

i am getting the follwing from the logs while running a script as post function for SubTask creation.

java.lang.NullPointerException: Cannot invoke method contains() on null object

at Script7.run(Script7.groovy:5)

The code used is working fine but throws exception in the logs

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.issuetype.IssueType

if ((issue.issueTypeObject.name == 'Web') || (issue.issueTypeObject.name == 'Email') || (issue.issueTypeObject.name == 'Maintenance'))  {
    if (cfValues['Translation(s)']*.value.contains("Vietnamese")) {
            IssueType issueType = ComponentAccessor.getConstantsManager().getIssueTypeObject("10903");
            for(subTask in issue.getSubTaskObjects()) {
                if(subTask.getIssueTypeObject().equals(issueType)) {
                    return false;
               }
            } 
            return true;
            }
      }

How can this be rectified?

Thank you!

Hi ,

I think the list of values returned by the custom field "Translations"  can be sometimes null as well thus you should do the null check as well in order to avoid NPE

if (cfValues['Translation(s)'] && cfValues['Translation(s)']*.value.contains("Vietnamese"))
