Can't find robot footprint?

When I run gmappingdemo.launch for my turtlebot2, I get the error "You must specify at least three points for the robot footprint, reverting to previous footprint" even though my footprint should be set. In my costmapcommonparams.yaml, I have robotradius set to 0.18. When I echo the /movebase/localcostmap/footprint topic I get:

Please don't answer questions with a new question. Moreover the question is 3 years old so you probably won't have an answer.

Please search other questions related on this site and if you don't find any answer ask a new one describing your problem and providing everything to reproduce your error so that people cna help you.
