NITRO0016Return H3 v2 redirect responses
H3 v2 prefers returned redirect() responses over sendRedirect(event, ...).
vite-doctor/nitromigrationwarnSuggestion
Why it happens
The H3 v2 response model uses returned Web API response values while sendRedirect remains a compatibility wrapper.
Fix
Return redirect(location, status) from the handler.
Example
Return an H3 v2 redirect
Before
export default defineHandler((event) => {
return sendRedirect(event, "/login")
})
After
export default defineHandler(() => {
return redirect("/login")
})
