Why this happens

Issue #522 on nksaraf/vinxi (open, created 2026-04-12). Developer deploying to Cloudflare Workers got opaque error messages; root cause was module scope restrictions (setInterval, DB pool, auth instances declared outside handler functions). Had to switch to Vercel because CF Workers error experience was 'pretty frustrating'. Good commercial content opportunity — many developers face this exact pain point.
