IPNS resolve does not query delegated HTTP routers

[Rinse12]

Environment

In our project we use IPNS-Over-Pubsub and maintain both kubo nodes and helia. We have rolled out a delegated http routers with support only for /providers since in kubo you don't need /ipns for IPNS provider query.

ipnsPubsubTopicRoutingCid = CID.createV1(0x55, sha256("floodsub:" + ipnsPubsubTopic))

Expected behavior

• When resolving an IPNS name using a delegated routing client (without /ipns endpoints), the resolver should query /routing/v1/providers/<ipnsPubsubTopicRoutingCid> to discover providers and dial them.
• The resolver should connect to the announced provider, join the IPNS pubsub topic

Actual behavior

• IPNS resolve fails with RecordNotFoundError.
• No /routing/v1/providers/* requests are made (provider query count stays 0).
• The resolver never connects to the provider (connections after resolve attempt: 0).

How to replicate

1. Clone https://github.com/Rinse12/delegated-routing-ipns-provider-repro
2. npm install
3. npm run start
4. Observe the logs

Notes

• The repro spins up:
  • A local delegated routing HTTP server that only serves /routing/v1/providers/*.
