Environment:
MacOS : 10.13.6
Golang : 1.11.8
Hyperledger Fabric : 1.4
Java : 1.8
Description:
I try to run an official JavaSDK Fabric app example.
I can deploy and run the app normally with the default configuration.
Then I make some changes in configtx.yaml (just some rules about generating blocks) and generate the binary tool configtxgen, then I use:
./configtxgen -profile TwoOrgsOrdererGenesis -outputBlock genesis.block
./configtxgen -profile TwoOrgsChannel -outputCreateChannelTx channel.tx -channelID mychannel
commands to regenerate channel.tx and genesis.block.
I use these new files to start the fabric network, and follow the steps of this page, but I get the following error while creating channel:
*org.hyperledger.fabric.sdk.exception.TransactionException: Channel mychannel, send transaction failed on orderer OrdererClient{id: 4, channel: mychannel, name: orderer.example.com, url: grpc://localhost:7050}. Reason: Channel mychannel orderer orderer.example.com status returned failure code 400 (BAD_REQUEST) during orderer next
Caused by: org.hyperledger.fabric.sdk.exception.TransactionException: Channel mychannel orderer orderer.example.com status returned failure code 400 (BAD_REQUEST) during orderer next*
The logs of orderer container say:
2020-08-26 10:25:33.469 UTC [orderer.common.broadcast] ProcessMessage -> WARN 009 [channel: mychannel] Rejecting broadcast of config message from 192.168.0.1:56440 because of error: error validating channel creation transaction for new channel 'mychannel', could not succesfully apply update to template configuration: error authorizing update: error validating DeltaSet: attempted to set key [Value] /Channel/Application/Org1MSP/AnchorPeers to version 1, but key does not exist
Anyone know the solution?
You have to update your Anchor peers too like they said on script.
cryptogen generate --config=./crypto-config.yaml
mkdir config
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./config/genesis.block
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./config/channel.tx -channelID mychannel
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./config/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./config/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
You can find details on build.sh script and have to uncomment out those lines.

Failed to generate channel configuration transaction...
Create channel failed
I'm having some troubles creating a channel in Hyperledger Fabric v1.4.3 without the use of Docker. I could succesfully generate keys, certs, genesis block and the various artifacts by simply executing cryptogen and configtxgen, then start orderer and peer. However, when I try to create a channel with command
peer channel create -c mychannel -o 127.0.0.1:7050
it fails due to "BAD_REQUEST -- error validating channel creation transaction for new channel 'mychannel', could not succesfully apply update to template configuration: error authorizing update: error validating Readset: existing config does not contain element for [Group] /Channel/application/SampleOrg but was in the read set.
Below the list of commands (executed from fabric-samples/first-network directory):
# cryptogen generate --config=./crypto-config.yaml
# export FABRIC_CFG_PATH=$PWD
# mkdir channel-artifacts
# configtxgen -profile TwoOrgsOrdererGenesis -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block
# export CHANNEL_NAME=mychannel
# configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
# configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
# configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
# sudo mkdir -p /var/hyperledger/production
# sudo chown -R $(whoami):$(whoami) /var/hyperledger
# orderer start
# export set FABRIC_CFG_PATH=$HOME/fabric-samples/config
# peer node start >> peerlog.log 2>&1 &
# peer channel create -o 127.0.0.1:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx
This is the output of the the peer terminal, after the attempt of the channel creation:
2019-10-01 12:51:11.955 CEST [ChannelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized

In the orderer terminal, subsequently:

Any help would be appreciated, I've tried all the solutions I've found online. Thank you in advance.
Edit
This is what I modified in orderer.yaml:
LocalMSPDir: /home/rfiorini/fabric-samples/first-network/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp
This is what I modified in core.yaml:
mspConfigPath: /home/rfiorini/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp
I have been following this link : http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html#troubleshoot for starting my first network, using byfn.sh file, and have executed all steps till
export CHANNEL_NAME=mychannel && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
The error that I am getting is:

I have tried variations of the command,
export CHANNEL_NAME=mychannelanother && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
export CHANNEL_NAME=mychannelanother && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $mychannelanother
export CHANNEL_NAME=mychannel && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $mychannel
I even tried creating a channel without using byfn.sh file, but got a different error

I modified the /home/himani/fabric-samples/first-network/crypto-config/ordererOrganizations/example.com/tlsca/tlsca.example.com-cert.pem doc by referring to this link : https://gerrit.hyperledger.org/r/#/c/18177/ , and executed the command again, but to no avail.
Are my certificates outdated? Where can I find the right ones? Is the issue something else?
UPDATE:
After referring to a solution provided to a similar problem, Hyperledger Fabric v1.1.0 byfn tutorial on Ubuntu 16.04, I brought down my network and tried to clean up artifacts but I couldn't execute those commands. Channel artifacts folder is empty.
I couldn't execute those commands
This command is meant to add files in channel-artifacts folder, but for some reason the folder was not created automatically. On creating one, with adequate permissions, the command executed and genesis block was created.
I don't know if you have solved it or not, but there are some mistakes there.

if you are following the tutorial, CHANNEL_NAME should be mychannel.
for the 3rd variations, it should be like this
export CHANNEL_NAME=mychannel && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
for creating channel, peer channel create can only be send inside docker container.
If you are sending directly from command line, try this
docker exec -it yourCliContainerName peer channel create -o orderer.example.com:7050 -c mychannelthis -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
but remember to start the container first.
hope this helps
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.
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 ?
Check fabric node logs to find clue:

I installed hyperledger fabric v1.1.0-rc1 using byfn.sh.
(Reference:
http://hyperledger-fabric.readthedocs.io/en/lastest/build_network.html)
But I got some failure. It's Fabric CA problem?
[executed]
./byfn.sh -m generate
./byfn.sh -m up
../bin/cryptogen generate --config=./crypto-config.yaml
export FABRIC_CFG_PATH=$PWD
../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
export CHANNEL_NAME=mychannel
./bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
my configtx.yaml is https://github.com/hyperledger/fabric-samples/blob/release-1.1/first-network/configtx.yaml
I faced a similar issue. What helped me was to start over.
Bring down the network: ./byfn.sh -m down
Clean up the generated artifacts
rm crypto-config
rm channel-artifacts
Then issue again the commands. This helped me, the channel.tx and other were successfully created. No need to change the configtx.yaml from the sample.
You don't have to delete files you just need to make sure that ./byfn.sh -m down was executed prior to steps in Crypto Generator section
