Hi all,
I would like to tag on a shipper transactions with additional dates, so I tried to run the beat with
tags: ["foo", "baz", "%{+yyyy}","%{yyyy.MM}","%{yyyy.MM.dd}",]
assuming that the variables are evaluated. However, the actual shipped tags are literally the strings "%{+yyyy}" 
Maybe somebody has an idea for me, what is failing here for me?
Cheers and thanks,
Thomas
