roslaunch failer

[aka-LJ]

hello,

I have built the package successfully and try to run the node within a ROS launch file.

however, I get the following error for running the package within a launch file.

here is the error message:
[firefly/kf_tracker-9] process has died [pid 4937, exit code -6,

here is how I call the node within the launch file, the filtered_cloud is remapped to a PointCloud2 msg.

<node name="kf_tracker" pkg="multi_object_tracking_lidar" type="kf_tracker" output="screen"> <remap from="/filtered_cloud" to="vi_sensor/camera_depth/depth/points"/>

I'm on 18.04 + Melodic, any suggestion is appreciated!
