In line 223 (previously 215) there's a special handling for the common case of a single group. I think the if-condition needs to be adjusted here to also check that there's no ISR config. Because if the functions isn't set there, ISR will not picked up (functions is just empty). This could happen if you set IRS at the adapter level.

If you don't have any route config, we'll never get into here because functions is empty (because of line 216)

We shipped incremental static regeneration on Vercel last week, but it was broken. Turns out there were a few extra hoops to jump through.
Brief explanation of the changes:
group, so that if you invalidate/fooyou simultaneously invalidate/foo/__data.json— this is assigned automatically__pathnamequery parameter.req.urlis reconstructed byadapter-vercelbefore the request is handed off to SvelteKit/fooor/foo/__data.jsonis being requested, while still allowing/fooand/foo/__data.jsonto be invalidate simultaneously, we need to create two Vercel routes for each SvelteKit route withisr.
