Hi Tapsi,
In theory this should work fine on a 2013 system as well, so I would suggest opening a support ticket at http://support.clickdimensions.com and requesting technical help on this. I'm inclined to think that it's not necessarily your process, but perhaps another plugin or entity that's throwing this error. However, it would be helpful if you could include a full screenshot of your workflow in the ticket as well.
Thank you!
