Workers prod bug: placement misroutes ctx.exports WorkerEntrypoint.fetch
WorkersI’m seeing a reproducible production-only routing issue with Workers.
1)
2)
Expected:
- (2) executes
Actual in production when
- (1) works
- (2) is misrouted to main
Live repro:
https://cloudflare-ctx-exports-bug-reproduction.white-meadow-a345.workers.dev/probe
Current sample output:
{"directRpc":"FROM_RPC_METHOD mode=no-props","directFetchText":"FROM_INDEX_DEFAULT","note":"Direct ctx.exports fetch should hit OutboundProbe.fetch and start with FROM_OUTBOUND_CLASS."}
Isolation so far:
- Local
- Production behaves correctly if
- Changing
Minimal repro repo:

Could someone from runtime/workerd help triage this?
