JavaScript interop calls cannot be issued at this time

It is forbidden to use JSRuntime during pre-rendering.

[Inject]
protected IJSRuntime JS { get; set; }

protected override void OnAfterRender()
{
   JS.InvokeAsync<bool>("paceDone");
   base.OnAfterRender();
}

System.InvalidOperationException: "JavaScript interop calls cannot be issued at this time. This is because the component is being prerendered and the page has not yet loaded in the browser or because the circuit is currently disconnected. Components must wrap any JavaScript interop calls in conditional logic to ensure those interop calls are not attempted during prerendering or while the client is disconnected."

How do I know that JSRuntime is unavailable? There are some solutions to this problem besides resource-intensive try { } ?
