hyperledger fabric devmode - hyperledger-fabric

I am trying to deploy chaincode in devmod on my ubuntu machine. I am following this tutorial.
The issue is when I use this command : CORE_CHAINCODE_LOGLEVEL=debug CORE_PEER_ADDRESS=localhost:7052 npm start
it shows the following error:
2018-09-20T16:27:18.292Z ERROR [lib/handler.js] uncaughtException: The "peer.address" program argument must be set to a legitimate value of <host>:<port>
Full logs can be found here:
https://hastebin.com/arerozesad.sql
I am following this tutorial:
https://hyperledger-fabric.readthedocs.io/en/v1.0.6/peer-chaincode-devmode.html

First, I hope you are using Fabric v1.1 or later as Node.js chaincode is not supported in v1.0.x.
The instructions you listed are for running Go chaincode.
For Node.js chaincode, your command should look like
CORE_CHAINCODE_ID_NAME="mycc:v0" node mycc.js --peer.address grpc://localhost:7052
You should be able to replace node mycc.js with npm start as well.
See https://github.com/hyperledger/fabric-chaincode-node#test-nodejs-chaincode for more information.

debug node js chaincode ...?

This link gives tutorial on debugging javascript chaincode in hyperledger fabric. I was able to debug my chaincode following it but recently I updated to fabric 1.2 and the peer channel list command
CORE_PEER_LOCALMSPID=Org1MSP CORE_PEER_MSPCONFIGPATH=/home/bct/fabric-samples/basic-network/crypto-config/peerOrganizations/org1.example.com/users/Admin#org1.example.com/msp peer channel list
fails with:
Fatal error when initializing core config : error when reading core
config file: Unsupported Config Type ""
I tried to go back to v1.1 but the problem persists. Can someone give me the complete list of configuration steps that may have been missed in tutorial video (which I was following) that make the debugging chaincode work.
Thanks in advance.
Finally, figured out that fabric sdk (https://github.com/hyperledger/fabric-sdk-node) has to be downloaded and configured before following the video tutorial in the question.

Error in instantiating fabcar chaincode in node, fabric 1.3

I am following this section of fabcar tutorial. When i run :
./startFabric.sh
It works like charm. But when i run following command to run node.js chaincode:
./startFabric.sh node
I get the error:
Error: could not assemble transaction, err proposal response was not
successful, error code 500, msg timeout expired while starting
chaincode fabcar:1.0 for transaction
I am using Fabric 1.3.0. Let me know how can i resolve this.
I got it worked. Actually a chaincode with same name and version was existing. So i just changed the version and it worked like charm.

Event Hub has been Shutdown on Fabric Writing your first Application

I am currently trying to run through the example first application for Hyperledger Fabric here -> http://hyperledger-fabric.readthedocs.io/en/release-1.1/write_first_app.html
I am unable to get past calling node invoke.js
Originally I was getting the same error as this question Error invoking chaincode using Node.js SDK [TypeError: Cannot read property 'getConnectivityState' of undefined]
But after reverting to grpc#1.9.1 I get the following result:
I am able to do everything up to the node query.js method and that returns successfully but can't quite get past this.
Node version: 8.11.1
Docker Version:
fabric client section of package-lock.json
FYI: I am trying to run on Windows 10 mostly using the docker toolbox bash, or a separate git bash CLI.
Last piece of info!
Even though the invoke js command fails with the above error, I can see that the PUT command to couch db does go through and car10 has been successfully added.
If I check the docker logs for peer0.org1.example.com I see the following:
So did it actually work?

Hyperledger on IBM Cloud, chaincode launched and waiting for registration

Code
Currently I followed this article to develop my BNA to IBM blockchain cloud platform (started plan). Unluckily, I got the error when I try to run this line of code:
composer network start -c admin#mynetwork-fabric -A admin -C ./creds/admin-pub.pem -f delete.card -n my_network -V 0.0.4
Error
I am very sure that all parameters are good, the full errors are:
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:
premature execution - chaincode (my_network:0.0.4) launched and
waiting for registration
Or sometimes the error is:
Error: Error trying to start business network. Error: No valid responses
from any peers.
Response from attempted peer comms was an error: Error:
REQUEST_TIMEOUT
I understand sometimes maybe there is a timeout, but I do not really got the launched and waiting for registration error.
P.S.
My hyperledger composer version is 0.19.
I also view this deploying tutorial, there might be some different commands, because of the different versions of Hyperledger Composer. I checked the composer hep to transfer the commands to running on composer 0.19.
Solution:
down grade composer-cli to 0.18.1
change your package.json, composer-cli to 0.18.1
npm install to create new bna
reinstall
restart
If you are using IBM Cloud Starter Plan, then you need to be using v0.18.1 of Composer not v0.19.
Also, this is the doc you should be following:

Error while updating business network in CLI tutorial

I am following along the Getting Started with Fabric Command Line and have run into a error I don't understand how to resolve. Any ideas?
In the section entitled "Update the deployed business network" an exception is thrown. The terminal output is below. The command used:
composer network update --archiveFile digitalproperty-network#0.0.7.bna --enrollId WebAppAdmin --enrollSecret DJY27pEnl16d
Note that the id is different from the tutorial as the 0.0.7 id was reported during the previous step while creating. The output continued...
Deploying business network from archive digitalproperty-network#0.0.7.bna
Business network definition:
Identifier: digitalproperty-network#0.0.7
Description: Digital Property Network

I've struggled to get the versions to match the tutorials - they seem inconsistent. Notably, the node (v6.9.5) and nodejs (v6.10.1) versions differ even though node is a symbolic link to nodejs and I notice 6.9.5 is in the stack trace. I'm not sure that difference is relevant to the problem.
Other version information:
Ubuntu 14.04.5
Docker version 17.03.1-ce, build c6d412e (manually installed as auto
install was down level)
docker-compose version 1.12.0-rc2, build 08dc2a4
I've seen exactly that error when Hyperledger Fabric isn't running. If docker ps doesn't show anything, run npm run startHLF in the sample-applications/packages/getting-started directory before trying again.
