hyperledger fabric first_network example create channel got BAD_REQUEST - hyperledger-fabric

Question

I have been following tutorial on hyper ledger website: https://hyperledger-fabric.readthedocs.io/en/release/build_network.html#behind-scenes.
I was able to run
./byfn.sh -m generate
./byfn.sh -m up
This setup run all the way through of showning the end.
like:
===================== All GOOD, BYFN execution completed =====================
_____ _ _ ____
| ____| | \ | | | _ \
| _| | \| | | | | |
| |___ | |\ | | |_| |
|_____| |_| \_| |____/
./byfn.sh -m down
Then I begun to follow the tutorial further to execute each line manually.
I have successfully executed:
cryptogen generate --config=./crypto-config.yaml
export FABRIC_CFG_PATH=$PWD
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
export CHANNEL_NAME=mychannel
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
CHANNEL_NAME=$CHANNEL_NAME DELAY=600 TIMEOUT=600 docker-compose -f docker-compose-cli.yaml up -d
docker exec -it cli bash
By now, I should have all the certs, channel tx and anchor peers generated and started all necessary docker containers.
then I executed
export CHANNEL_NAME=mychannel
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
in the cli container and got:

hannel2 -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabr c

Error: Got unexpected status: BAD_REQUEST
Usage:
Got no idea what when wrong here. There are no further or meaningful error message shown except BAD_REQUEST.
I was running it on a vagrant environment with box of ubuntu 16.04 x64.
The fact that ./byfn.sh -m up went through means my env can run the first sample no problem. But cannot create channel manually. Any idea what when wrong?
I have deleted all docker containers and rerun, then got this message:
Error: got unexpected status: BAD_REQUEST -- error authorizing update: error validating ReadSet: readset expected key [Group] /Channel/Application at version 0, but got version 1
It seem to be mismatched version for peer update, how to solve this?

Answer 1

./byfn.sh -m restart -c (channelName)
replace channel name by your own channel name if u have ran (./byfn.sh -m up) previously and if its your first time doing it then use ./byfn.sh -m up(in first-network in folder)

Answer 2

It might be because the certificates aren't replaced in right place. I suggest you to pull the following repo. And try running your byfn from there.
git clone -b issue-6978 https://github.com/sstone1/fabric-samples.git

Answer 3

What is the value of $CORE_PEER_TLS_ENABLED in your peer channel create command?

Answer 4

I had the same problem, and I fixed it by doing:
$ docker rmi -f $(docker images -q)
to remove the docker images.
Then, from the official website I downloaded the fabric samples, and the binaries again, the commands I used were:
git clone -b master https://github.com/hyperledger/fabric-samples.git
curl -sSL [insert link from the website] | bash -s 1.1.0-rc1
Then, it should work with you.

Answer 5

When I used fabric, usually not removing docker container makes a lot of problems.
So I recommend removing docker-container, use that
docker ps -aq | xargs docker rm -f
But you are careful about using another docker container.
