Resolving index.html regularly fails

[Klustre]

I regularly get the following error after hot reloading took place. The result is a blank panel. Perhaps it didn't build yet before the reload takes place.

Manually reloading the plugin through UDT shows the panel as expected without error.

​ Uncaught Error: Cannot resolve module: index.html.
