Hammer CLI

Problem:
After upgrading to 1.19 I can’t query facts via hammer. I’m running into following error:

[ ~]$ hammer host facts --name=otd2001.xeop.de
Error: undefined method `collect’ for " Matrox Electronics Systems Ltd. MGA G200EH":String

Expected outcome:
Foreman 1.18:
[ ~]$ hammer host facts --name=aesdmp02.dbag.prod

RHEL 7.5 (latest patch)

I have to cut out the fact data. But the result block was valid.
