Not able to get last custom field value using getChangeItemsForField getFrom()

[Rob_Duncan]

I am trying to see the last value for a specific custom field with the code below but I m getting an error.  Could someone advise how to resolve this?

import com.atlassian.jira.issue.changehistory.ChangeHistoryManager;
import com.atlassian.jira.issue.history.ChangeItemBean;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;

//For test
Issue issue = ComponentAccessor.getIssueManager().getIssueByKeyIgnoreCase("EPIC-10");
String fieldName = 'Who'

def ChangeHistoryManager= ComponentAccessor.getChangeHistoryManager();

List<ChangeItemBean> changeItems
changeItems = ChangeHistoryManager.getChangeItemsForField(issue, fieldName)
if (changeItems.size()>0) {
 return changeItems.get(0).getFrom()

}

Hello,

What is the error?

Hi @Alexey Matveev, the following:

It is a static compilation error. Just run this script. It should work.

@Alexey Matveev, thank you.  It is returning null despite size returning 2 with the expected value in getCreated(), but I can't seem to get the value of the From or To string... 

import com.atlassian.jira.issue.changehistory.ChangeHistoryManager;
import com.atlassian.jira.issue.history.ChangeItemBean;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;

//For test
Issue issue = ComponentAccessor.getIssueManager().getIssueByKeyIgnoreCase("EPIC-10");
String fieldName = 'Who'

def ChangeHistoryManager= ComponentAccessor.getChangeHistoryManager();

List<ChangeItemBean> changeItems
changeItems = ChangeHistoryManager.getChangeItemsForField(issue, fieldName)
if (changeItems.size()>0) {
 return changeItems.get(changeItems.size()-1).getFrom()

}

Try like this:

import com.atlassian.jira.issue.changehistory.ChangeHistoryManager;
import com.atlassian.jira.issue.history.ChangeItemBean;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;

//For test
Issue issue = ComponentAccessor.getIssueManager().getIssueByKeyIgnoreCase("EPIC-10");
String fieldName = 'Who'

def ChangeHistoryManager= ComponentAccessor.getChangeHistoryManager();

List<ChangeItemBean> changeItems
changeItems = ChangeHistoryManager.getChangeItemsForField(issue, fieldName)
if (changeItems.size()>0) {
 return changeItems.get(changeItems.size()-1).getFromString()

}
