I'm trying to update a .bna file, however, I'm facing this issue when I run the following command :

composer network upgrade -c PeerAdmin@hlfv1 -n xxx -V 0.0.2

it says the following : 

Upgrading business network definition. This may take a minute...

Error: Error trying to upgrade 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: could not find chaincode with name 'wecashup') Command failed

I sincerely don't know to resolve that, I've already updated the version on my json file ...but still the same errors.

{

"engines": { "composer": "^0.19.13" }, "name": "xxx", "version": "0.0.2", "description": "WecashUp blockchain", "scripts": { "prepublish": "mkdirp ./dist && composer archive create --sourceType dir --sourceName . -a ./dist/wecashup.bna", "pretest": "npm run lint", "lint": "eslint .", "test": "nyc mocha -t 0 test/*.js && cucumber-js" }, "keywords": [ "composer", "composer-network" ], "author": "Paris", "email": "parismollochristondis@gmail.com", "license": "Apache-2.0", "devDependencies": { "composer-admin": "^0.19.13", "composer-cli": "^0.19.13", "composer-client": "^0.19.13", "composer-common": "^0.19.13", "composer-connector-embedded": "^0.19.13", "composer-cucumber-steps": "^0.19.13", "chai": "latest", "chai-as-promised": "latest", "cucumber": "^2.2.0", "eslint": "latest", "nyc": "latest", "mkdirp": "latest", "mocha": "latest" } }

My composer version is 19.13

  • Have you run the command `composer network install` to install the new code onto the Peer before starting it? Or have you run the startFabric.sh script since running the install command? – R Thatcher Aug 20 '18 at 12:30
  • I start by startfabric (after cleaning the docker) and then I install on the PeerAdmin and only after all that I execute the upgrade the command – Paris Mollo Aug 20 '18 at 13:00
