Hi, 

I am using Kendo react grid in my project. It work fine in my local, but produces the following error on scrolling the grid after build and deployment.

Uncaught TypeError: Cannot read properties of null (reading 'element')
    at p (drag-n-drop.js:84:24)
    at useDraggable.js:149:9
    at HTMLDivElement.<anonymous> (useDraggable.js:217:9)

Why am I getting this error after build and how is it working fine in my local? Please suggest a way to resolve this.

Regards

Mansi

Hello, Mansi,

Thank you for the report.

This seems to be connected with the following issue that is also observed in the Scheduler:

https://github.com/telerik/kendo-react/issues/1202

They both originate from the same useDraggable functionality we use internally.

Currently, there is no workaround available, if one is found it will be added to the issue.

Apologies for the inconvenience this may have caused you.

Regards,
Stefan

Hi Stefan,

How am I not getting this error in my local with npm start?

Hello,

The error may also occur in a local environment, but it could be difficult to reproduce.

Another reason could be variable issues while bundling the application.

We can provide more specific information on why it occurs only there after the team locates the issue.
