TanStack Router's `redirect()` and `notFound()` throw special errors caught by the router. Move them outside the try block or re-throw in the catch

Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Fires on throw redirect(...) or throw notFound(...) located lexically inside a try block but not inside a catch clause. The rule does NOT verify whether the surrounding catch re-throws router errors. False positive: a catch that already isolates and re-throws redirect/notFound — the throw inside try is still flagged for visibility.

Fix prompt

Use this once validation confirms the diagnostic is real.

Move the throw outside the try, or in the catch re-throw router errors first: catch (err) { if (isRedirect(err) || err instanceof Response) throw err; ... }. Otherwise a broad catch swallows the special error TanStack Router uses internally to perform the navigation. See https://tanstack.com/router/latest/docs/framework/react/guide/navigation
