I am trying to instantiate a chaincode from a Fabric Java SDK Client using code from this
example
When i am trying to add imports inside chaincode ie
github.com/hyperledger/fabric/core/chaincode/lib/ci
I am getting error from the peer
2018-05-30 17:03:24.813 UTC [endorser] simulateProposal -> ERRO 038 [mychannel][6326fbfe] failed to invoke chaincode name:"lscc" , error: Failed to generate platform-specific docker build: Error returned from build: 1 "chaincode/input/src/github.com/ify/ify.go:40:2: cannot find package "github.com/hyperledger/fabric/core/chaincode/lib/cid" in any of:

/chaincode/input/src/github.com/hyperledger/fabric/core/chaincode/lib/cid (from $GOPATH)
/opt/gopath/src/github.com/hyperledger/fabric/core/chaincode/lib/cid
where should i install the packages inside peer in order to be visible from the go builder?
You have to put everything in vendor, as stated in the coding guidelines: Hyperledger Fabric uses Go Vendoring for package management.
In this way you can import external libraries in the chaincode.

While trying to install chaincode using Fabric v2.1, I am encountering an error. Does anyone face similar issues? My peer is running fine and able to join the channel as well. I am able to list the channel details as well.
Note: I am doing Native installation without using docker images for running orderer and peer.
Highly appreciate for your support and looking forward to hear from you.
Error:
chaincode install failed with status: 500 - error in simulation: failed to execute transaction 44688cc50afeda03e3f5e7735ae650030952477b6bdfce83064582f42bec6c84: could not launch chaincode _lifecycle.syscc: error building chaincode: error building image: failed to get chaincode package for external build: could not get legacy chaincode package '_lifecycle.syscc': open /home/vagrant/ledger/ORG2/peer1-org2/ledger/chaincodes/_lifecycle.syscc: no such file or directory
I got this error after upgrading from 1.4. In my case the problem was in the old config file for the peer.
Make sure you have next lines in your core.yaml:
chaincode:
...
# enabled system chaincodes
system:
_lifecycle: enable
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.
While deploying the chaincode using fabric-java-sdk , if the chaincode contains external dependencies peer throws the below error:
2019-01-11 06:10:46.220 UTC [endorser] SimulateProposal -> ERRO 2ed [mychannel][c310d352] failed to invoke chaincode name:"lscc" , error: Failed to generate platform-specific docker build: Error returned from build: 1 "chaincode/input/src/anjy/anjy.go:10:2: cannot find package "github.com/rs/xid" in any of:

"
error starting container
error starting container
The error says it was unable to find the dependencies in the $GOPATH. However my $GOPATH contains those dependencies, yet the chaincode builder is unable to pick it up.
We have to create a "vendor"-folder in the same path the chaincode is stored in.
https://hyperledger-fabric.readthedocs.io/en/v1.1.0-alpha/chaincode4ade.html#managing-external-dependencies-for-chaincode-written-in-go
Suppose the chaincode is stored in below file structure:
../src/chaincode/chaincode.go
then the vendor folder goes inside the below structure: [with dependency to the files in the vendor folder]
./src/chaincode/vendor
Since I tried the new feature of Fabric v1.3: key-level-endorsement from this doc, I have to generate my key-level endorsement policy by KeyEndorsementPolicy.Policy() function.
However, I cannot instantiate the chaincode after I have imported the package github.com/hyperledger/fabric/core/chaincode/shim/ext/statebased
Here are the error logs:

I know that it means ccenv container lack this dependence, so I tried to add my vendor directory under gopath to chaincode path directory of my instantiate request. Then I got another try and there are still errors:

I suspect that there are still some c/c++ libraries missing in ccenv image.
So, how can I generate a key-level endorsement policy []byte without this KeyEndorsementPolicy? or, how can I import this shim/ext/statebased package?
That's because of a bug from fabric-sdk-node, here is the link.
After upgrade to fabric-client#1.3.0, problem solved:
npm install fabric-client#1.3.0
npm install fabric-ca-client#1.3.0
need help on chaincode instantiation which is dependent on other go packages like golang/protobuf and pkg/errors. Below is the error i am getting in the peer logs,

/opt/gopath/src/github.com/pkg/errors
I've already mounted these to the peer docker and are present at these /opt/gopath/src/github.com/golang/protobuf/proto locations
In order to compile chaincode the peer starts new container using fabric-ccenv base image. As a result mounted to the peer folder /opt/gopath/src/github.com/golang/protobuf/proto is not available at runtime.
It's better to vendor the proto package with the chaincode, try to run following command in the root folder of your project:
govendor add github.com/golang/protobuf/proto
This command should create subfolder vendor/github.com/golang/protobuf/proto and populate it with all necessary files.
Just try to install your chaincode again, required dependencies will be shipped with your source code and are availalbe in runtime.
