ScriptRunner Postfunction Rule Custom Email: How to display custom field as rich text

[Mike_Low]

GOAL: Configure a custom email (via scriptrunner postfunction rule) to render a custom field in rich text. i.e. have the custom field display in the email the same way it does when viewing it in a Jira issue.

Configuration thus far: Email template successfully pulls custom field value into email using the below script:

<% out <<
${helper.render(issue.getCustomFieldValue(
com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Development Details")))}
%>

After looking at the adaptavist scriptrunner documentation it looks like you are able to have a field render in the rich text by using the following (example using description field):

${helper.render(issue.description)}

How can I apply this helper.render script to the custom field value above?

Additional Info:

- Custom email is setup with HTML text

Fixed by applying  ${helper.render(issue.getCustomFieldValue(
com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Development Details")))}
