I am following the tutorial on: https://hyperledger.github.io/composer/v0.19/applications/web To implement a frontend to my chain code. But when I try to put in the command:
composer network start --networkName perishable-network --networkVersion 0.2.7-deploy.0 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1
It gives me the error:
✖ Starting business network definition. This may take a minute... Error: Error trying to start business network. Error: No valid responses from any peers. Response from attempted peer comms was an error: Error: 2 UNKNOWN: chaincode error (status: 500, message: is not a valid endorsement system chaincode) Command failed
When I did composer install on my bna however I got this information which I am using in the network start command.
✔ Installing business network. This may take a minute... Successfully installed business network perishable-network, version 0.2.7-deploy.0
Command succeeded
How can I fix this error?
You are trying to use Composer 0.20 with Hyperledger Fabric 1.1. Unfortunately they are not compatible. You should either downgrade to Composer 0.19 or upgrade your fabric for 1.2
