Hello I have this project that requires users to add waypoints onto a world map dashboard which will send coordinates to a small vehicle powered by a Jetson Nano which would then navigate to those coordinates. It will also contain a UI group that will have gauges connected to external sensors to dis…

As you have found the worldmap is not a track store. If you need to save points you need to do that at the server side (when they are sent with a click).

No problem, I appreciate the help

My guess it has something to do with the functions that contain this line of code: var flowMarkersObjectArray = flow.get('MarkersObjectArray')||[]; I…
