Kendo grid, odata v4, grouping - e.slice is not a function

Hi,

@Oleg

Unfortunately, we do not have such demo and I am afraid that we cannot provide a resolution for your technical question in regard to Kendo UI Grid.

As far as I am aware, the Kendo UI Data Source component has a partial support (as shown here), but not in its entirety, for working with oData v4.

Please follow my suggestion and consult the respective product and/or community forums.

Thanks for your understanding.
