Clone issue Post Function - clearing the Original Estimate field for cloned issues

[tifonas-katrina]

Hi,

I am at combination of Jira v.7.2 and script runner v.5.3

Previous admins have created a cloning mechanism which creates a new issue coping all the fields from parent issue.

End users now need the Original Estimated field to be purged upon cloning.

Any idea how this may be achieved?

The below lines don't function.

def cf = customFieldManager.getCustomFieldObjects(issue).find {it.name == 'Original Estimate'}
issue.setCustomFieldValue(cf, null)

P.S:I am new here and can't understand how script runner works. Documentation didn't help me either.

Regards,

K.
