hyperledger fabric discovery service failing endorsement

Hello everyone i am trying to use service discovery with the node js client to generate transaction proposals, the problem i am having is that when discovery generates the endorsement plan it sends the proposals to the same peer and fails to endorse, here is one of the endorsement plans generated, idk why but peer names are all wrong

When the NodeSDK application is running first level and is working with a fabric network in a local virtual environment where the peer addresses are seen as "localhost", the port addresses in the virtual environment must also be unique. In the docker-compose when mapping the virtual port to a real port it is easiest to use the same address. Notice in the following example that port address defined the virtual environment is the same as the host mapping.

    environment:
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - CORE_PEER_ID=peer0.org2.example.com
      - CORE_PEER_ADDRESS=peer0.org2.example.com:8051
      - CORE_PEER_LISTENADDRESS=peer0.org2.example.com:8051
      - CORE_PEER_GOSSIP_ENDPOINT=peer0.org2.example.com:8051
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org2.example.com:8051
      - CORE_PEER_LOCALMSPID=Org2MSP
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/peerOrg2/msp
      - CORE_PEER_GOSSIP_BOOTSTRAP=peer0.org2.example.com:8051

    ports:
      - 8051:8051

Keep in mind that the host name must also be mapped from the virtual name to "localhost", this is done by using the connect option "aslocalhost:true" when the channel is initialized. 

await channel.initialize({discover:true, asLocalhost:true})

Hope the following will help

Could we see a debug log of when the channel was initialized. It would be helpful to see the Discovery results being read in from the Peer's Discovery Service. The Peer's name seen in the endorsement plan does not come from the Discovery Service, this is a name assigned by the NodeSDK and these should be unique and contain the host and port. Since they are not unique, the same Peer is indeed being used.
