Hi @Or L ,
Thank you for reaching out to us!
"fabric-ccenv:latest" tag has been deprecated by Hypereldger Fabric Community. Hence, during chaincode instantiation, it fails to pull the image from docker hub. More details are here
We are working on fixing the issue and republishing the template. We will update you as soon as the template will be updated. Meanwhile, you can follow the workaround steps suggested here
Please let us know if you face any issue while running the workaround script.
