Once you have configured your custom runtime Fabric environment for your multi-Org, multi-channel setup, you can then create the requisite Hyperledger Composer

问题 I'm having some problems trying to deploy a bna file using the fabric composer. First I tried using my own HyperLedger 0.6 instance, creating a connection profile and then using the composer-cli to deploy a bna and I got the following error during the composer network deploy command: "TypeError: Cannot read property 'fail' of undefined" Then I removed all my docker images and containers, made sure everything was updated and I tried the getting-started script and I got the exact same error.

I have tried different commands such as adding a participant, adding an asset and performing a transaction and everything seems to work correctly. However, when I try to issue a new identity I do not get the results that I expect. I execute my Node.js application with the following code: var businessNetwork = new BusinessNetworkConnection(); return businessNetwork.connect('admin@tutorial-network')
