Possible MetaData Issue with Lighthouse

See original GitHub issue

I was looking through a recent Lighthouse peerstore dump from Altona and found 14 teku nodes in the peerstore. All 14 had a reputation of 0 & metadata = null. I’m wondering if there is a possible issue with the MetaData req/resp method. 🤷‍♂️

Here is an example of a teku entry:

  {
    "peer_id": "16Uiu2HAmRaVfypo834Kovh4mQErjTzigyAnri4618wpEke3bXftD",
    "peer_info": {
      "_status": "Healthy",
      "reputation": 0,
      "client": {
        "kind": "Teku",
        "version": "v0.12.0-dev-5380e888",
        "os_version": "linux-x86_64",
        "protocol_version": "ipfs/0.1.0",
        "agent_string": "teku/teku/v0.12.0-dev-5380e888/linux-x86_64/oracle_openjdk-java-11"
      },
      "connection_status": {
        "Connected": {
          "in": 0,
          "out": 1
        }
      },
      "listening_addresses": [
        "/ip4/xx.x.x.xxx/tcp/9000/p2p/16Uiu2HAmRaVfypo834Kovh4mQErjTzigyAnri4618wpEke3bXftD"
      ],
      "sync_status": {
        "Synced": {
          "info": {
            "status_head_slot": 65255,
            "status_head_root": "0xf9aa4c155d92640eae4ff6f9262625e9ccd092f328cb84284bc558a915f3ec1d",
            "status_finalized_epoch": 2013,
            "status_finalized_root": "0x7d5a7d2ee690fa2fd50cf0c18e4c28d674e5c33b2d184cbe36cec135219b6891"
          }
        }
      },
      "meta_data": null
    }
  }

For comparison, here is an example of a Prysm node:

 {
    "peer_id": "16Uiu2HAmLvREVVcPJGbpRmvEMxV8AJy1s8fn9LRPXVB9FBo9xYaW",
    "peer_info": {

        "os_version": "unknown",
        "protocol_version": "ipfs/0.1.0",
        "agent_string": "Prysm/v1.0.0-alpha.13/a9bbbae19abac0c3c8cf7c4213b949172f97cf57"
      },
      "connection_status": {
        "Connected": {

          "out": 1
        }
      },
      "listening_addresses": [

      ],
      "sync_status": {

          }
        }
      },

    }
  }

Here is a Nimbus node:
