TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of URL. Received undefined

I’m getting this error:

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of URL. Received undefined In my index page https://svelte-house-marketplace.vercel.app/. Im 99% that is caused by the Slidy component.

When I run build in the SvelteKit project, I get these warnings:

Did you know what’s happening?
