Convector Framework CLI returns error when installing chaincode

I am very new to the Hyperledger Fabric and Convector Framework and I have followed this tutorial:
https://worldsibu.github.io/convector/modules/getting_started.html
When I try to use the CLI tool and run the command (test is my chaincode name):
npm run cc:start -- test 1
It gives the following errors:
Installing Chaincode test version 1.0 at org1
Error: Error endorsing chaincode: rpc error: code = Unknown desc = access
denied: channel [] creator org [org1MSP]
...
Installing Chaincode test version 1.0 at org2
Error: error getting endorser client for install: endorser client failed to
connect to localhost:7151: failed to create new connection: context deadline
exceeded
I have not changed the configs and MSPs.
What is going wrong and how should I start to resolve the problem? Any guidance is appreciated!
#shole that documentation is now deprecated, you can use http://docs.worldsibu.com/convector for the latest versions.
About your error that usually happens when the environment gets corrupted and keeps cryptographic materials from a previous installation, try re-running npm run env:restart and try again.

The answer and comments in this post should help you if you are using Composer v0.16.x
This tutorial should help with the format of the connection.json file.
If you are using v0.17.x, you will need this version of the tutorial.
UPDATE:
Composer v0.19 is now the latest version with many enhancements and some breaking changes. The tutorial has been updated accordingly and the revised tutorial is here.

Error Promise is rejected: when running balance-transfer (hyperledger) with nodejs

I am following the steps to run the blockchain code from balance-transfer in the sample codes provided by hyperledger.
https://github.com/hyperledger/fabric-samples/tree/release/balance-transfer.
Things work smoothly when I run it with golang but I get the following error when I run it with node.js.
error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: error starting container: Failed to generate platform-specific docker build: Error returned from build: 254 "npm WARN example_cc#1.0.0 No repository field.
The error occurs when the chaincode is instantiated on the channel.
I am using node v8.6.0 and npm v5.3.0.
Any idea what is going on?
Thanks in advance.
It turns out the code written in node.js has been removed in their latest release. I guess there was a problem with it.
