rmf_fleet_adapter 2.1.8-1jammy.20250326.000335
Description of the bug
When running any of the demo simulations, whenever a task is dispatched, the fleet adapter dies due to a segmentation fault when the robot has to make a turn on the pathway.
Steps to reproduce the bug
- Launch RMF using 'ros2 launch rmf_demos_gz_classic office.launch.xml'
- Dispatch a task using CLI: 'ros2 run rmf_demos_tasks dispatch_delivery -p pantry -ph coke_dispenser -d hardware_2 -dh coke_ingestor --use_sim_time'
Expected behavior
No response
Actual behavior
