I followed the steps in the documentation to modify the topics for the elevation map and the topic for publishing the target point, but encountered the 'process has died' issue. How can I solve this?

Has anyone encountered this issue? After setting a target point in Rviz, the terminal running art_planner_ros reports a 'process has died' error. There is also an elevation map below the robot, and the parameters in params.yaml have been configured correctly.
