TypeError: Failed to Register a ServiceWorker in HTML Export

[jkort]

Hello,

If I open a static HTML export file in Chrome, I get this error:

TypeError: Failed to register a ServiceWorker: The URL protocol of the current origin ('null') is not supported.
at Stunning program.jl.html:23

which I assume is this:
navigator.serviceWorker?.register(document.head.querySelector("link[rel='pluto-sw']").getAttribute("href"), { scope: "./" }).catch(console.warn)

This is fine to ignore, we can't register a serviceworker on file:// URLs. Since the SW is only an optimization, it is not a problem.
