Summary
Better fix for preactjs/preact-www#979
If the
--prerenderUrlsfile exists (defaults to/prerender-urls.json) on disk, but for some reason cannot produce a result (wrong format, throws, etc.), this PR ensures the build fails, rather than continues w/ a warning while using the default (prerendering only/with no passed-in data).Does this PR introduce a breaking change?
Technically yes, though it's the right change to make. It will only break builds for those that have the file on disk, but a result cannot be obtained from it. They should remove the file or fix it.
