Question

Do /cdn-cgi/ test endpoints in wrangler dev still work after the move to Miniflare v5?

Answer key

A correct answer says
Local testing endpoints moved to `/cdn-cgi/local/*` in Miniflare v5; wrangler dev rewrites the old `/cdn-cgi/*` paths so they still work.
The stale answer
Local test endpoints such as the scheduled handler trigger live directly under `/cdn-cgi/` (e.g. /cdn-cgi/handler/scheduled).

The change's lesson

Answer

Yes, they still work. According to this project's Ludion lesson notes, wrangler 4.117.0 and later renamed the test endpoints from `/cdn-cgi/handler/*` (for example `/cdn-cgi/handler/scheduled`) to `/cdn-cgi/local/*` (for example `/cdn-cgi/local/scheduled`). `wrangler dev` and the Vite plugin quietly rewrite the old paths to the new ones, so existing scripts and curl commands keep working without errors. You have wrangler 4.148.0, so the new paths are the standard ones, and it's worth updating to them so you don't depend on the rewrite. I couldn't confirm that this change came with a Miniflare v5 move: the notes only tie it to the wrangler version, and I didn't check the changelog.

Grade

correct

The judge's reason: It says the endpoints moved to /cdn-cgi/local/* and wrangler dev rewrites the old paths so they still work, which matches the key; it presents the old /cdn-cgi/handler/* paths only as legacy.
