Hello everyone,
I faced one error "Unable to register data type 'BusMultiObjectTracker1' for 'TrialRef/Tracks' due to the following error: The number of elements must be greater than zero for this data type.",which I cann't figure it out. I don't get it.
I've spent many many days on my model and it's not still working.
Please take a look at this issue if you are familiar with it.
The layout is like below:

Any help is much appreicated!

'BusMultiObjectTracker1' is likely a Simulink.Bus object. Check it in base workspace or your Simulink Data Dictionary. The number 2 Outport block "Tracks" is specified to have that bus. Now, it seems that the actual signal connected to that Outport block does not have any bus element.

Use BusCreator and BusSelector block to interface between Bus and signal elements
Change the data type of the Outport block to change from "Bus: <object name>" to any other data type.
