any idea what this error could be?

I am using D455 intel realsense camera and I have made changes to the config file as well as launch files. My publishers are not being published and am getting the above warning

The algorithm assumes that your system already has a working localization system to get the various transformations, such as camera to base and base to odom. However, it seems that this is not the case.

I recommend writing a URDF file to include all the static TFs, and if you don't have it yet, add a localization package as well.
