Need help with Laser Filter

edit

I am having issues with kinetic-devel branch package. When I try to launch median_filter_5_example.launch is:

[ERROR] [1667875380.665928716]: Couldn't find filter of type laser_filters/MultiChannelMedianFilterFloat [ERROR] [1667875381.759529779]: LaserArrayFilter not configured [ERROR] [1667875381.759594557]: Filtering the scan from time 1667875379.815046787 failed.

When I try to launch test_scan_filter_chain.launch. I get: PARAMETERS

/array_filter_chain: [{'type': 'laser_...
/bad_filter_chain: [{'type': 'laser_...
/intensity_filter_chain: [{'type': 'laser_...
/interp_filter_chain: [{'type': 'laser_...
/mask_filter_chain: [{'type': 'laser_...
/rosdistro: kinetic
/rosversion: 1.12.17
/shadow_filter_chain: [{'type': 'laser_...

No processes to monitor shutting down processing monitor... I'm not sure where to get MultiChannelMedianFilterFloat from or why other launch file doesn't work.
