I am trying to run fabric network locally using minifab tutorial. While making my first transaction, I am encountering following error.
Here is my command
minifab invoke -p '"invoke","a","b","4"'
Error Details
non-zero return code
Error: chaincode argument error: invalid character 'i' looking for beginning of value
Usage:
peer chaincode invoke [flags]
windows version of minifab requires below command(with backslashes)
minifab invoke -p \"invoke\",\"a\",\"b\",\"4\"
This will solve the problem.

I'm currently trying to get the example for hyperledger fabric working. I get as far as starting the chaincode successfully using the deployCC script, and get the expected printout of all the cars after running the script. However, when I get to the next step of manually querying the network, I run into issue. I've run the exports for org1 as specified, and verified that the paths match and the tls cert and mspconfig exist in those locations. However, when I try to run the query command:
peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'
I get the following error printout:
Error: error getting endorser client for query: endorser client failed to connect to 0.0.0.0:7051: failed to create new connection: context deadline exceeded
I would expect to get the same printout as at the end of the deployCC script, and I can't figure out why that isn't happening. Any help in diagnosing this is appreciated!
If it matters, I'm running this in a VM with Ubuntu 20.04. All the prerequisites are fresh installations of the latest versions from the last couple of days.
Liam, if you are able to see all the cars at the end of deployCC, then it might be an environment variables issue. Remember that you have to execute the peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}' command in the same terminal where you ran deployCC because the environment variables are all set in that window.
We can do a couple of things to confirm:
Paste the output from DeployCC at the end, right after (and including)
Querying chaincode on peer0.org1...
Using organization
Print the following environment variables from the terminal window where you are executing deployCC and from the terminal window where you are executing the peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}' command
CORE_PEER_LOCALMSPID,
CORE_PEER_TLS_ROOTCERT_FILE,
CORE_PEER_MSPCONFIGPATH,
CORE_PEER_ADDRESS.
See if they match?
I am new to Hyperledger Fabric and going thru their study tutorial https://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html .
Issue : I made changes in query.js and invoke.js to replace local host with my IP Address which I reverted back to original . Now when I run startFabric.sh script , I am getting following error : " Error: error getting chaincode code fabcar: failed to determine platform type: Unknown chaincodeType: UNDEFINED " .
I have googled the issue whole day but still unable to solve . Please let me know how I may solve this issue .
You aren't specifying a chaincode type, the command is ./startFabric.sh <chaincode type> which you can specify as something like javascript or golang
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:

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.
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:
https://console.bluemix.net/docs/services/blockchain/develop_starter.html#deploying-a-business-networks-on-starter-plan
I am trying to configure hyperledger composer with multi peer. But when I have started the hyperledger fabric, getting following response.

I have used COMPOSE_FILE=docker-compose.yaml instead of COMPOSE_FILE=docker-compose-cli.yaml due to this error came. After modifying it working as expected.
Is it possible your error may be captured by the answers posted here -> Error when try to instantiate chain-code on Hyperledger Fabric - perhaps making sure there's no 'space' in your directory name (as shown above) may help / setting the variable explicitly?
I had a similar error recently and it related to having some conflicting containers already active. In a section of the following it explains how to remove potentially conflicting containers which I followed to remove my occurrence of this issue. https://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html
upgrade the docker-compose or reinstall it
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
It solves the problem for me.
In my case, docker-composer was missing. Installing it solved the issue.
