Error trying to instantiate composer runtime. Error: No valid responses from any peers. for Multi organization hyperledger fabric 1.1

Question

I am trying to setup hyperledger fabric + composer setup with multi organizations locally. The steps I followed to setup hyperledger network is below.

Generate crypto materials and channel

• cryptogen generate --config=./crypto-config.yaml configtxgen -profile OrdererGenesis -outputBlock ./channel-artifacts/genesis.block
• configtxgen -profile Channel -CreateChannelTx ./channel-artifacts/channel.tx -channelID ehrchannel
• configtxgen -profile Channel -outputAnchorPeersUpdate ./channel-artifacts/Hospital1MSPanchors.tx -channelID ehrchannel -asOrg Hospital1MSP
• configtxgen -profile Channel -outputAnchorPeersUpdate ./channel-artifacts/Hospital2MSPanchors.tx -channelID ehrchannel -asOrg Hospital2MSP

  Start docker containors for two organisations Execute Below commands on cli containor

• peer channel create -o orderer.ehr.com:7050 -c ehrchannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/ehr.com/orderers/orderer.ehr.com/msp/tlscacerts/tlsca.ehr.com-cert.pem

Having all peers join the channel with setting appropriate env veriables - peer channel join -b ehrchannel.block Updating anchor peers for two organisations by setting env variables

• peer channel update -o orderer.ehr.com:7050 -c ehrchannel -f ./channel-artifacts/Hospital1MSPanchors.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/ehr.com/orderers/orderer.ehr.com/msp/tlscacerts/tlsca.ehr.com-cert.pem

After that I have followed Hyperledger composer document to configure composer. But on step 17 on the doc, I am getting an error

composer network start -c PeerAdmin@ehr-network-hos1 -a marbles-network.bna -o endorsementPolicyFile=/tmp/composer/endorsement-policy.json -A admin1 -C admin2/admin-pub.pem -A admin2 -C admin2/admin-pub.pem

What are the potential issues? Thank you so much in advance.

Answer 1

What versions of Composer and Fabric are you using ? If you are using Composer v0.18.2 you need to have the GA version of Fabric v1.1.

The releases document for Composer details the compatible versions of Composer and Fabric. https://github.com/hyperledger/composer/releases

Also you might have a typo in your command ... -A admin1 -C admin2/admin-pub.pem -A admin2 -C admin2/admin-pub.pem are you specifying the wrong folder for admin1 ?

Answer 2

Check fabric node logs to find clue:

docker logs [orderer/peer/...]
