I try to follow the tutorial of the Hyperledger Fabric python SDK, but get a problem when creating channel. The error I got is shown in the following:
Exception: [status: BAD_REQUEST
info: "error applying config update to existing channel 'businesschannel': error authorizing update: error validating ReadSet: proposed update requires that key [Group] /Channel/Application be at version 0, but it is currently at version 1"
]
How can I fix it?
The issue is that you didn't remove your previous config before creating a new channel i.e businesschannel. See this line in your error error applying config update to existing channel 'businesschannel. If you are using docker then try below commands:-
docker rm -f $(docker ps -aq)
docker network prune -f
docker volume prune -f

I'm practicing upgrading network components (orderer and peers) following the official hyperledger fabric docs. In particular I'm following this link to upgrade the orderer. I'm able to follow all steps, but I get an error at the last step when bringing up the orderer:
/test-network docker logs b0d56da4a9f082bc7c5c0dea1e81ba3bf30c55be8f306b0a27986c706a056da4
2022-10-24 14:53:07.899 UTC [orderer.common.server] Main -> ERRO 001 failed to parse config: Error unmarshaling config into struct: 2 error(s) decoding:
* cannot parse 'General.ListenPort' as uint: strconv.ParseUint: parsing "'7050'": invalid syntax
* cannot parse 'General.TLS.Enabled' as bool: strconv.ParseBool: parsing "'true'": invalid syntax
These are the commands I'm executing in order:
#1. Stop the ordering node.
docker stop $ORDERER_CONTAINER
#2. Back up the ordering node’s ledger and MSP.
docker cp $ORDERER_CONTAINER:/var/hyperledger/production/orderer/ ./backup/orderer/$ORDERER_CONTAINER
docker cp $ORDERER_CONTAINER:/etc/hyperledger/fabric/msp/ ./backup/msp/$ORDERER_CONTAINER
#3. Remove the ordering node container.
docker rm -f $ORDERER_CONTAINER
#4. Launch a new ordering node container using the relevant image tag.
docker run -d -v ${PWD}/backup/orderer/$ORDERER_CONTAINER/:/var/hyperledger/production/orderer/ \
-v ${PWD}/backup/msp/$ORDERER_CONTAINER/:/etc/hyperledger/fabric/msp/ \
--env-file ./envord.list \
--name $ORDERER_CONTAINER \
hyperledger/fabric-orderer:$IMAGE_TAG orderer
After I execute the last command I get:
b0d56da4a9f082bc7c5c0dea1e81ba3bf30c55be8f306b0a27986c706a056da4
The container is created but fails to start with the error presented above. Any clues?
I found the problem. When I exported the variables from the orderer container before bring it down for the update, for some reason they where saved as follow:
ORDERER_GENERAL_EXAMPLE='example value'
The values for all variables were enclosed between single quotes. I removed those single quotes and the problem was solved.
I am trying to init the chaincode on hyperledger fabric 1.4.5 setup with k8s, however getting error as
"Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: Failed to generate platform-specific docker build: Failed to pull hyperledger/fabric-ccenv:latest: API error (404): manifest for hyperledger/fabric-ccenv:latest not found: manifest unknown: manifest unknown
"
Please anybody help me on this issue
latest tag has been deprecated. You can add
CORE_CHAINCODE_BUILDER: hyperledger/fabric-ccenv:your_version
under peer's environment in compose file.
This issue is resolved in Fabric v1.4.8 as it will now look for fabric-ccenv:1.4 by default, instead of fabric-ccenv:latest.
See the v1.4.8 release notes for more details.
The tag was removed. The workaround is to pull the matching version and tag it locally as latest.
docker pull hyperledger/fabric-ccenv:1.4.0
docker tag hyperledger/fabric-ccenv:1.4.0 hyperledger/fabric-ccenv:latest
Following the build your first network tutorial on hyperledger docs when I type
$ ./byfn.sh up
I get following warning
LOCAL_VERSION=1.2.0
DOCKER_IMAGE_VERSION=1.2.1
=================== WARNING ===================
Local fabric binaries and docker images are
out of sync. This may cause problems.
===============================================
and finally the script fails with this error
Error: failed to create deliver client: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: context deadline exceeded
!!!!!!!!!!!!!!! Channel creation failed !!!!!!!!!!!!!!!!
Restart the bootstrap process by cding into the folder fabric-samples/scripts and run bootstrap.sh again like this
$ ./bootstrap.sh
This made my images to get synced like this in the output
LOCAL_VERSION=1.3.0
DOCKER_IMAGE_VERSION=1.3.0
You need to first delete the existing and then download the higher version of Hyperledger Fabric. You can run the following commands to do this:
cd fabric-samples
rm -Rf bin
curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh | bash -s 1.3.0
./scripts/bootstrap.sh
I am trying to configure hyperledger composer with multi peer. But when I have started the hyperledger fabric, getting following response.

I have used COMPOSE_FILE=docker-compose.yaml instead of COMPOSE_FILE=docker-compose-cli.yaml due to this error came. After modifying it working as expected.
Is it possible your error may be captured by the answers posted here -> Error when try to instantiate chain-code on Hyperledger Fabric - perhaps making sure there's no 'space' in your directory name (as shown above) may help / setting the variable explicitly?
I had a similar error recently and it related to having some conflicting containers already active. In a section of the following it explains how to remove potentially conflicting containers which I followed to remove my occurrence of this issue. https://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html
upgrade the docker-compose or reinstall it
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
It solves the problem for me.
In my case, docker-composer was missing. Installing it solved the issue.
Part of the answer (!) to this question is that I must know (in advance) that this is a problem, identify the images that I must pull (here's Orderer) and then retag them all with "latest". This seems sub-optimal. I know this problem because I've experienced it before, but... I'm being a noob and following along here:

Please revise the tutorial page to reference this additional pre-req
Or parameterize scripts to take DOCKER_TAG={{VALUE}}
Or am I missing something?
These instructions could be:
Identify the latest version for your architecture using "fabric-orderer" as a template:
https://hub.docker.com/r/hyperledger/fabric-orderer/tags/
In my case the latest tag is x86_64-1.0.3 and I'm using bash, so:
TAG={{THE CORRECT VALUE}} // In my case x86_64-1.0.3
for IMAGE in orderer couchdb peer ca tools
do
docker pull hyperledger/fabric-${IMAGE}:${TAG} && \
docker tag \
hyperledger/fabric-${IMAGE}:${TAG} \
hyperledger/fabric-${IMAGE}:latest
done

What you missing is the step where you have to download binaries, see "Download Platform-specific Binaries".
curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap-1.0.3.sh | bash
