问题
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:
- Setup crypto-config.yaml and generated crypto-material (crypto-config)
- Setup fabric-ca-server-config.yaml by updating
keyfile&certfile. started CA server - 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?

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.
