Click on Variables
Click on the tab Groovy variable

Paste in the script below

Custom field example

import com.atlassian.jira.component.ComponentAccessor
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def CF_ID = 10301
def CF = customFieldManager.getCustomFieldObject(CF_ID)
def cfValueOfIssue = issue.getCustomFieldValue(CF)

return new String(cfValueOfIssue.getBytes("UTF-8"));

Change the custom field variable to the id of your system
