when I click on the filter icon of the grid I get this error

 

Microsoft.JSInterop.JSException: Could not find 'showAnimationGroupAsync' in 'window.TelerikBlazor'.
Error: Could not find 'showAnimationGroupAsync' in 'window.TelerikBlazor'.

 

I am using Telerik.UI.forBlazor 2.17.0

 

and i am referencing the local JS file _content/Telerik.UI.for.Blazor/js/telerik-blazor.js

 

I am not sure what is causing this error, any help would be appreciated 

 

Thanks

Hello Andrew,

The following article summarizes the known reasons and solutions for such problems: https://docs.telerik.com/blazor-ui/troubleshooting/js-errors

If going through them does not help, I recommend you open a support ticket and send us a small runnable sample that shows the problem so we can take a look at the concrete situation.

Hi Andrew,

In such a case, it is likely that there is a timing issue due to the extremely low latency of the localhost "connection" and perhaps removing the "defer" attribute from the script will help with that. It is not a mandatory thing, we add it to the documentation with the hope to speed up people's pages a bit.
