Enonic version: 6.8.0
OS: OSX
I’m using the attachmentUrl in the portal lib creating a URL to a video like this:
<source src="[@attachmentUrl id=source._id /]" />
It works just as expected when visiting the site but in the log i get the following StackTrace 
, am I doing it wrong or is it a bug in Enonic?
