I use vite@8.0.1. This worked in vite@7.

Expected behavior 🤔

Success build.

will be fixed by #2080

[nicolas-geysse]

Same crash here on the published @solidjs/start@2.0.0-alpha.2, hitting it via the rolldown-vite@7.3.1 opt-in (rolldown 1.0.0-beta.53) on Vite 7 — identical stack, manifest.js:38 Cannot read properties of undefined (reading 'source') through @solidjs/vite-plugin-nitro-2 buildApp. The transform phase completes fine (7350 modules), it's purely the SSR manifest plugin.

PR #2080 looks like it fixes exactly this, but it isn't in any published version yet — npm latest/alpha is still 2.0.0-alpha.2, which predates the 2026-05-12 merge. Any chance of an alpha.3/beta cut that includes it? Happy to test against it.

One note in case it helps others landing here: #2080 gates the fix on the Vite major (v7 keeps the in-memory START_CLIENT_BUNDLE path, v8+ reads the manifest from disk), so the rolldown-vite@7.x alias would still hit the old path even after publish — the supported route looks like Vite 8 proper.
