使用 Node.js 在 Hyperledger Fabric 中创建通道时出错

Question

I am looking to setup a simple Hyperledger Fabric network without using docker and trying to create channel by following this tutorial using Node.js. Steps i performed:

1. Setup crypto-config.yaml and generated crypto-material (crypto-config)
2. Setup fabric-ca-server-config.yaml by updating keyfile & certfile . started CA server
3. Setup configtx.yaml by defining one orderer and one organization. Created genesis block and configuration transaction

Now by when i run above tutorial node.js code, i get error on order terminal & as response of node.js call:

2019-01-09 16:16:54.619 IST [msp] DeserializeIdentity -> INFO 007 Obtaining identity

2019-01-09 16:16:54.619 IST [orderer/common/broadcast] Handle -> WARN 008 [channel: firstchannel]

Rejecting broadcast of config message from 127.0.0.1:44198 because of error: Failed to reach implicit threshold of 1 sub-policies, required 1 remaining: permission denied

I tried many changes and still getting same error. Same error also appear while creating channel through terminal using ./peer channel create -o localhost:7050 -c firstchannel -f ./channel.tx

Here is my channel.tx converted in JSON.

How this can be resolved?

Answer 1

I got it worked! Actually in orderer.yaml , i set LOG to DEBUG and now i can see the problem in channel creation well descriptive.

There were multiple things which i needed to improve but main thing was that in orderer.yaml , GenesisMethod was set to file , so it was creating system channel and was looking the signature of the OrdererMSP admin. Changing GenesisMethod to provisional got channel creation worked.
