[Solved] Issue with KendoReact TaskBoard.

[nEMO]

Hello Telerik team,

I’m reporting an issue with KendoReact TaskBoard.

# Videos
- UI bug (horizontal scroll flickering):  
https://go.screenpal.com/watch/cOfuhgnOGeJ

- Console error during drag & drop:  
https://go.screenpal.com/watch/cOfuhknOGeM

# Issue
When dragging items in TaskBoard with horizontal scrolling enabled:

- Horizontal scrollbar flickers during drag & drop
- Sometimes a runtime error occurs

# Error
TypeError: Cannot convert undefined or null to object  
at TaskBoard.js / useDraggable onDragEnd

# Expected
Smooth drag & drop without UI flickering or console errors.

Hi,

I examined the provided videos and tested the following demo by following the same steps in order to reproduce the console error and flickering:

• https://demos.telerik.com/kendo-react-ui/taskboard/overview/func?theme=default-ocean-blue

However that the flickering and error did not reproduce on my end. I have attached a video of my test to this response. I suspect that the issue might occur on a specific browser, my test was carried out on Chrome and Safari. Can you please provide the used browser and version in which you are able to reproduce the issues? This will enable me to test again and reproduce the issues on my end as well.

Regards,
Filip
