setIssue() is throwing java.lang.NullPointerException when used with WorkflowTransitionUtil workflow

Hi Team,

With the use of 

WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) ComponentAccessor.getComponent(WorkflowTransitionUtilImpl.class)

setIssue() is throwing java.lang.NullPointerException.

Can someone help with the correct method/value to be passed.

Below is the code used:

import com.opensymphony.workflow.WorkflowContext;
import com.atlassian.jira.workflow.WorkflowTransitionUtil;
import com.atlassian.jira.workflow.WorkflowTransitionUtilImpl;
import com.atlassian.jira.util.JiraUtils;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.component.ComponentAccessor;
 
String currentUser = ((WorkflowContext) transientVars.get("context")).getCaller()
//WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) JiraUtils.loadComponent(WorkflowTransitionUtilImpl.class)
WorkflowTransitionUtil workflowTransitionUtil = (WorkflowTransitionUtil) ComponentAccessor.getComponent(WorkflowTransitionUtilImpl.class)

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField epicLink = customFieldManager.getCustomFieldObjectsByName('Epic Link').getAt(0)
MutableIssue parent = (MutableIssue) issue.getCustomFieldValue(epicLink);
if (parent != null) {
    log.warn "${parent.getSummary()}"
    log.warn "${parent.getStatus().getSimpleStatus().getName()}"

    def isDevBacklogStatus = parent.getStatus().getSimpleStatus().getName() in ['New']
    log.warn "${isDevBacklogStatus}"

    if (isDevBacklogStatus) {
        workflowTransitionUtil.setIssue(parent)<----Issue is here
        workflowTransitionUtil.setUserkey(currentUser)
        workflowTransitionUtil.setAction(11)
        if (workflowTransitionUtil.validate()) {
            log.warn "inside validate"
            workflowTransitionUtil.progress()
        }        
    }
}

Regards

Welcome to the Atlassian Community!

The NPE on that line means that the "parent" variable contains a null, not the issue object that the function needs.

So my guess would be that the parent issue the script is running against does not have an Epic link (or the code on the line "MutableIssue parent = ..." is wrong, although it looks ok at a glance to me)
