The path gets planned, however the robot drifts away and the path is constantly corrected by the algorithm till I receive a fatal error that the robot is stuck in a position from which it cannot move.

The terminal in which rviz was run from gives the following error : "Invalid argument passed to canTransform argument source_frame in tf2 frame_ids cannot be empty"

Can somebody give me some direction to proceed in?

Thanks in advance!

What OS/ROS distro? What algorithm/package? Real robot or simulation? Which robot? What does your launchfile look like? Some more details on the error?

The rviz error points to an empty frame_id in a msg that should be visualized, but I guess this shouldn't be the problem. Try hunting the msg down.

Actually, I believe you might be able to solve your problems without answering most of the questions asked in the previous comment. That doesn't change the fact that you need to provide more information. Apparently, you have problems with costmap configurations. Can you share the parameters you used
