Message Check ERROR!

I get the error Message Check ERROR! when I run roslaunch fsd_common_meta trackdrive.launch.
In the picture below, I run the following 3 turns from left to right :

roslaunch fssim auto_fssim.launch
roslaunch fssim_interface only_interface.launch
roslaunch fsd_common_meta trackdrive.launch

Hello, I followed your steps to run the code and did not reproduce the above issue. Have you changed anything in interface? From your picture, I see the /fssim/track is not subscribed by interface. Message Check ERROR! will only be shown when topic /map is empty, which is transmitted by interface from /fssim/track in code here
Could you provide more information about how you modify the code?
