These three errors occur on random basis in the REPL tool inside the Telerik UI for Blazor documentation:

• Unhandled exception rendering component: Could not find 'TelerikBlazor initMediaQuery' ('TelerikBlazor' was undefined).
• InvalidOperationException: A suitable constructor for type 'BlazorRepl.UserComponents._Main' could not be located.
• System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.AspNetCore.Components.RenderTree.RenderTreeDiffBuilder.AppendDiffEntriesForFramesWithSameSequence(DiffContext& diffContext, Int32 oldFrameIndex, Int32 newFrameIndex)

Possible workarounds include:

• Clear the browser cache.
• Load the documentation page again to use the correct browser cache.

Blazor REPL import all static assets - both from packages and CDNs as normal JS files. The tool should know which files are modules and which are not.

Example:

The BlazorSize package is not working in the REPL: https://blazorrepl.telerik.com/mmYdEHFR31t74oWj55  


Resizing the browser doesn't update my label and I don't see any errors in the UI, but I do see this in F12...
