Error when creating channels

[user1234-code-arch]

I tried running the new version of Fablo and I encountered this error message while trying to build chain code, I've tried changing the docker image but it didn't work. I am running on an M1 Mac but I am using x86_64 architecture to run it. I've attached the error message here.

No need to build the chaincode

Any help to resolve this would be appreciated.

That sounds pretty unusual. What Fabric version do you use? Starting from 2.5 arm64 images for Fabric are available, and everything should work without any compatibility layer (native M1). For versions lower than 2.5 Fablo pre-fetches chaincode base images, since they are not available by default with Rosetta. And my guess is, since you are using x86_64 on M1, something fails with downloading chaincode base Docker images. You can try pulling images manually:

docker pull "hyperledger/fabric-nodeenv:$FABRIC_NODEENV_VERSION"
docker pull "hyperledger/fabric-javaenv:$FABRIC_JAVAENV_VERSION"
docker pull "hyperledger/fabric-baseos:$FABRIC_BASEOS_VERSION"

Samples are for Node, Java and Go - pick what is needed. Env values are in your Fablo target directory: fablo-target/fabric-docker/.env.

Then start your network again and let us know if it helped.

Hi, sorry for the delay in response but i tried the above and it still didnt work. I pulled the latest version from github and now I am able to use fabric 2.5 so I am running it nativly without using rosetta but it wont allow me to start the docker images. This is the error i am seeing now:
============ 🚀 Starting network 🚀 ==============

-- update -- i was able to sort the above problem by specifying the platform in the yaml file for fablo but now i am facing another problem when trying to create a channel this is the log i am seeing :

I tried to look into the logs of the orderer and this is what i am seeing, is there a way to resolve this :

PANI [orderer.common.server] Main -> Bootstrap method: 'file' is forbidden, since system channel is no longer supported
panic: Bootstrap method: 'file' is forbidden, since system channel is no longer supported

any help would be much appreciated please.

I was trying to reproduce it and run on MacBook M1 with no fabric images downloaded, but I didn't get any error (
log.txt). I had no images at the beginning, and after running fablo, all downloaded images were for arm architecture - which is correct. I was using fabric 2.5.9, and Docker desktop 4.12.0, Docker 20.10.17.

Maybe you could try to remove all docker images (incl both fabric and fablo), and then follow the same flow for the same fabric version?

So:

1. Delete all docker images
2. Download fablo with curl -Lf https://github.com/hyperledger-labs/fablo/releases/download/2.0.0/fablo.sh -o ./fablo && chmod +x ./fablo
3. Init network with Node chaincode: ./fablo init node
4. Start the network: ./fablo up
