Channel creation fails in Hyperledger Fabric v1.2

I'm trying to start an Hyperledger Fabric network in v1.2 with a network generated by myself (with binary configtxgen). The network starts correctly and no component indicates an error.

However, when I try to create a new channel, an error occurs at the orderer level (one of the following three errors) and no channel is created.

Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Group]  /Channel/Application/Org1MSP but was in the read set

Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Group]  /Channel/Application but was in the read set

Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Value]  /Channel/Consortium but was in the read set

To create the channel, I use the Go SDK on the master branch and follow the same procedure as for functional tests.

Any help would be greatly appreciated.

I got the solution from JSKIM. Since you are using the fabric v1.2, the orderer will create a default channel when the orderer node started up with the genesis block.

I guess you are using configtxgen to generate your own channel artifacts but ignore the naming rules of the channel. So when your exec into your orderer's container:

docker exec -it <orderer's container ID> bash

and cd into the chains directory, which is set to /var/hyperledger/production/orderer/chains by default. You will notice that there is already a channel exits.

Here is the solution:

configtxgen -profile testOrgsOrdererGenesis -channelID testchannel -outputBlock ./crypto-config/ordererOrganizations/orderer.block
configtxgen -profile testorgschannel -channelID mychannel-outputCreateChannelTx ./crypto-config/ordererOrganizations/mychannel.tx

when you generate the genesis block, using channelID to specific it. Or you can rename your channel when your create channel configuration transaction.

I finally managed to pass this error by changing the name of the generated channel. However, this does not explain why some names do not work.
