Thanks I've alrady found it. Replacing this line 

$textutils.htmlEncode($issue.getCustomFieldValue($customfield), false)

 with this

$customFieldManager.getCustomFieldObject("customfield_id").getValue($issue)

solved the problem. But why that error not fixed in the tutorial https://developer.atlassian.com/server/jira/platform/adding-custom-fields-to-email/
