Broken in Svelte Kit

[websocket98765]

Heads up. This component is broken in the new Svelte Kit:

The client gives an error:

500

is not a valid SSR component. You may need to review your build config to ensure that dependencies are compiled, rather than imported as pre-compiled modules

The component works fine for me on SvelteKit.

Doesn't work for my Svelte Kit app as well, the slider keeps sticking to the first index, I am updating the bound array programmatically upon user input, might be the issue.
