Discovery Service:

discovery: { 
        enabled: true, 
        asLocalhost: false 
    }

asLocalhost is false because all orgs are hosted on different hosts and are in docker swarm network. But i get this error when call the add asset invoke function.

The network topology is 5 orgs with 2 orgs with 1 peer without orderer and 3 orgs with 2 peers each with orderer. Orderers are the part of peerOrganization itself. And each organization has its own CA. What can be the cause of this error?

Updated Discovery:

await gateway.connect(ccp, {
  wallet,
  identity: username,
  discovery: {
    enabled: true,
    asLocalhost: true
  },
  clientTlsIdentity: 'freight'
})

const network = await gateway.getNetwork('supplychain-channel')
console.log(network)

Running client in docker environment within same network the fabric is running solves the above issue

Dockerfile

FROM node:10.24
WORKDIR /usr/src/app
COPY package*.json ./
RUN apt-get update || : && apt-get install python -y
RUN npm install
COPY . .
EXPOSE 9080
CMD [ "node", "server.js" ]

First RUN is important because node image doesn’t include python and fabric node sdk requires python for some modules like pkcs11, resolves errors gyp ERR! find Python checking if "python3" can be used occurred while installing dependencies.

docker-compose.yml

version: "2.1"

networks: 
  supplychain:
    external: 
      name: supplychain

services: 
  api:
    image: api:1.0
    build: 
      context: "client/"
    networks: 
      - supplychain
    ports: 
      - 9080:9080

setting asLocalhost: false and urls of peers to "url": "grpcs://peer0.freight.example.com:9051" the peers are discovered by the client.

await gateway.connect(ccp, {
      wallet,
      identity: username,
      discovery: {
        enabled: true,
        asLocalhost: false
      }
    })

DNS names ending example.com will not resolve unless you have entries for them in your local hosts file:

https://en.wikipedia.org/wiki/Example.com

The node names need to be resolvable and accessible by your client (and by other nodes since they will want to communicate with each other). If all of those addresses are mapped from private (e.g. Docker) networks to the same port number on your local host's network, you should be able to enable asLocalhost, which will simply cause the discovery service to treat and host names it receives as the localhost address (but leave the port number unchanged). Alternatively, you could make those addresses resolvable by either:

Giving them real public network addresses; or
Adding entries for them in your client's hosts file
