Custom field as filler in scriptrunner script

[helen levich]

I have customer listener script that updates fixVersions from epic to story. It works fine.

I need to add criteria that will only allow set fixVersoins from epic to story only when
'Merge' custom field is set to "Yes".
'Merge' is checkbox field.

I added following lines. But it does not work. Could you please take a look? Thank you

def CustomField customField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName('Merge');
def value = issueObject.getCustomFieldValue(customField);

if (epicissue.getIssueType().getName() == "Epic")

issueLinkManager.getOutwardLinks(epicissue.id).each { issueLink ->

MutableIssue issue = issueLink.getDestinationObject() as MutableIssue;

if (issueLink.issueLinkType.name == "Epic-Story Link" &&
issue.getIssueType().name == "Story" && value == "Yes"

Additionally tried this
issue.getCustomFieldValue('Incremental Dev Merge') == "Yes"

Here is script

if (epicissue.getIssueType().getName() == "Epic")

issueLinkManager.getOutwardLinks(epicissue.id).each { issueLink ->

if (issueLink.issueLinkType.name == "Epic-Story Link" &&

//issue.getCustomFieldValue('Incremental Dev Merge') == "Yes"

)
{

def currentValue = epicissue.getFixVersions()

issue.setFixVersions(currentValue);

issueManager.updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED, false)

boolean wasIndexing = ImportUtils.isIndexIssues();
IssueIndexingService indexing = (IssueIndexingService) ComponentAccessor.getComponent(IssueIndexingService.class)
indexing.reIndex(issue)
ImportUtils.setIndexIssues(wasIndexing)
}
}
