Severity Not at all severe... just a curiosity.

Addtional Context: When using Svelte 3.29.0 the issue is not reproducible.

5.0.1 is not the latest version of rollup-plugin-svelte, but judging by those error messages, you're not using version 5 anyway. And I highly doubt that this would be related to what version of Svelte you are using.

https://github.com/sveltejs/rollup-plugin-svelte/blob/master/CHANGELOG.md describes what changes you need to make to your Rollup config when updating to later versions.

https://github.com/sveltejs/sapper-template/tree/rollup contains the latest official version of the Sapper template, updated for rollup-plugin-svelte version 7.
