INN-5054 [BUG] [SSR] ReferenceError: exports is not defined

Thanks for the detailed report, @dualjack!

This one's actually a bit tricksy for us as our build is currently a single output that tries to support CJS and ESM; for pure-ESM environments this can sometimes be an issue, though most are a little more forgiving.

Switching to the ideal dual build also means stripping some of our very generous support for earlier TS/Node versions, so it'll have to be reserved for a breaking change in v4.

I've added #1005 which serves as an integration test for that version of SvelteKit to ensure v4 supports SSR properly there.

#920 is the PR to watch for that release; it's likely it will ship as a break with very few code-level changes required.

Hello,
Any news on this bug?

[jpwilliams]

Hi @bfovez!

v4 (#920) is close to being cut, which will resolve this. 🙂
