Empty peers array returned by /network/status endpoint

[linconvidal]

Context & versions

The /network/status endpoint returns an empty peers array. According to Mesh API specifications, a peer represents a node's connection and is a required field within NetworkStatusResponse.

This issue occurs in the mainnet environment (and likely affects other environments), potentially impacting all Java versions.

Steps to reproduce

1. Started application and waited for sync
2. Called /network/status
3. Checked out the response

Actual behavior

{
    ...
    "peers": []
}

Expected behavior

{
    ...
    "peers": [
        {
            "peer_id": "preprod-node.play.dev.cardano.org" // example from latest rosetta TS
        }
    ]
}

same behaviour:

{
   "current_block_identifier" : {
      "hash" : "710fc90e8041daf2bfdcf60ffcd7951ac7efff8e015da585540544fe275f3443",
      "index" : 11895822
   },
   "current_block_timestamp" : 1747885838000,
   "genesis_block_identifier" : {
      "hash" : "5f20df933584822601f9e3f8c024eb5eb252fe8cefb24d1317dc3d432e940ebb",
      "index" : -1
   },
   "peers" : []
}

Small update regarding this bug ticket, it is a known limitation. We had a discussion and we decided to fix this in a proper way, since Cardano has P2P (Peer 2 Peer) number of nodes that a passive cardano-node is connected to is a potentially 10 - 50 if not more and the list is dynamic. It would be quite easy to read those static bootstrap nodes from bootstrap nodes from topology.json file from cardano-node and return those values but those are only bootstrap nodes, actual nodes that cardano is connected to is much bigger list and it could be even different after bootstrap nodes (hence this is the whole point how P2P works).

We are working on downstream support in yaci-core library for this and then we will fix this bug / limitation in the rosetta java project.

Here is the revelant ticket from yaci-core project: bloxbean/yaci#114
