Fix getStaticPaths error in one route blocking other matching routes in dev by astrobot-houston · Pull Request #17189 · withastro/astro

astrobot-houston · 2026-06-24T19:22:54Z

Changes

In dev mode, when multiple routes match a URL pattern, an error thrown inside one route's getStaticPaths() no longer prevents other candidate routes from being tried. Previously, any non-routing error was immediately re-thrown, causing valid sibling routes to return a 500 instead of their correct response.
The fix stores the first non-routing error and defers re-throwing it until all candidates are exhausted without a match, so the error still surfaces when there's genuinely no valid route.

Testing

Added packages/astro/test/units/routing/dev-match-fallthrough.test.ts with two cases: one verifying that route B is matched when route A's getStaticPaths throws, and one verifying the error is still re-thrown when no valid alternative exists.

Docs

No docs update needed; this is a dev-mode bug fix with no API or user-facing behavior change beyond the bug itself.

…tching other routes in dev\n\nWhen multiple routes match a URL pattern in dev mode, an error thrown by one\nroute's getStaticPaths() would immediately propagate, preventing other valid\ncandidate routes from being tried. Now the error is stored and the loop\ncontinues; the error is only re-thrown after all candidates are exhausted.\n\nFixes #9819
