Invalid argument "/world" passed to canTransform argument source_frame in tf2 frame_ids cannot start with a '/' like warning

OS: Ubuntu 20
ROS: Noetic

I setup and built the FUEL algorithm in my system, but when I start the simulation as given in the Readme I am getting the following error when I run roslaunch exploration_manager rviz.launch

[ WARN] [1703668613.069205315]: Invalid argument "/world" passed to canTransform argument source_frame in tf2 frame_ids cannot start with a '/' like:

I am getting this error in RVIZ

And in another terminal I am getting the below when I run roslaunch exploration_manager exploration.launch

hello,I have facing an issue as you. Do you have an answer or do you have any suggestion to fix this bug?

[lightkid]

replace "/world" by "world"

[JaBerrin]

you need to locate to this file: FUEL / uav_simulator / Utils / odom_visualization / src / odom_visualization.cpp In this file, find something like: *.frame_id = string("/world"). you should remove "/" in all those statements. but you do not need to do so for line 369. Then save the file, catkin and run again, the warning will not exist.
