Wrangler error with C3 scheduled worker

When creating a scheduled worker with C3, upon running Wrangler with --test-scheduled and visiting http://localhost:8787/__scheduled?cron=*+*+*+*+*, I get the following error:

[wrangler:inf] GET /__scheduled 200 OK (36ms)

I've seen Walshy's reply on the forums, and the fix PR is merged, so I tried with wrangler@beta, but I get a more severe error now.
