What is the peer name If we add two members | amazon managed blockchain | REST Server

Question

I set up hyperledger fabric network in amazon managed blockchain using this document. I have used this as rest server. I have configured peer name as peer1 here. It was worked properly. Later I added one more member using this document. Now member 1 and member 2 should endorse the transaction.

docker exec cli peer chaincode instantiate -o $ORDERER \ 
-C ourchannel -n myjointcc -v v0 \
-c '{"Args":["init","a","100","b","200"]}' \
--cafile /opt/home/managedblockchain-tls-chain.pem --tls \
-P "AND ('Member1ID.member','Member2ID.member')"

Now I edited this config file as "peers":["peer1", "peer2"]. But I am getting the following error,

[2020-09-02 05:54:20.915] [ERROR] invoke-chaincode - Error: Peer with name "peer2" not assigned to this channel

What should I used instead of peer2? Help me to fix this issue.

Answer 1

you may have missed the step of joinning the peer to the channel:

docker exec cli peer channel join -b /opt/home/ourchannel.block \
-o $ORDERER --cafile /opt/home/managedblockchain-tls-chain.pem --tls

Both org1 and org2 need to run the following command on their respective Hyperledger Fabric clients to join their peer nodes to the channel
