Function prepareErrorPage

prepareErrorPage(
    event: IncomingBrowserEvent,
    response: ReactOutgoingResponse,
    container: IContainer,
    snapshot: ResponseSnapshotType,
): Promise<void>
Prepare the error page to render.

Error pages are prepared separately because their handler is different from the normal page handler: it takes an error as the first argument and the event as the second. StoneError is handed over as the fallback, for an error the application declared no page for.
Parameters
- event: IncomingBrowserEvent
  The incoming HTTP event.
- response: ReactOutgoingResponse
  The outgoing HTTP response.
- container: IContainer
  The service container.
- snapshot: ResponseSnapshotType
  The response snapshot.
Returns Promise<void>
