Chaincode for Developers tutorial error while instantiate chaincode

Question

This is a follow-up question for "Chaincode for Developers Cli error terminal 3". I am doing Chaincode for Developers tutorial and I am getting the following error when I run the command peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc on. terminal 3.

Output for command peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc:

Error: Error getting (myc) orderer endpoint: Error endorsing GetConfigBlock: rpc error: code = Unknown desc = chaincode error (status: 500, message: "GetConfigBlock" request failed authorization check for channel [myc]: [Failed to get policy manager for channel [myc]])

Output for the command:

peer chaincode install -p chaincodedev/chaincode/sacc -n mycc -v 0

I had to comment out the line

command: /bin/bash -c './script.sh

in the file "docker-compose-simple.yaml in order to run the command

docker exec -it cli bash.

Can anyone tell me how to solve this?

Answer 1

Well, I can see a few problems which might the root cause for the error you described. First of all please note, that during instantiate command:

peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc

you are not pointing to the ordering service, since instantiate is an endorsement transaction eventually it has to be submitted to the ordering service and therefore it should be something like this:

peer chaincode instantiate -o ordererEndpoint:7050 -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc

Note that error you received gives you a hint, since it says that wasn't able to obtain configuration block:

Error: Error getting (myc) orderer endpoint: Error endorsing GetConfigBlock: rpc error: code = Unknown desc = chaincode error (status: 500, message: "GetConfigBlock" request failed authorization check for channel [myc]: [Failed to get policy manager for channel [myc]])

Additionally please make sure that myc is existing channel and you have correctly created it beforehand. You can simply do:

peer channel list

to retrieve a list of channels peer was joined to.

Answer 2

The script that you disabled had the commands for creating the channels and joining peer to the channel, which are pre-requisites for doing invokes with the chaincode.

Answer 3

I think your problem is caused by the version of image. You're using 1.0.1, and you should change to 1.0.0. Check that the version code is

sudo docker images

Answer 4

If you are using docker toolbox on Windows7 to run developer tutorial the end-of-line notation needs to be change to be unix compatible in the scripts.sh. You can use notepadd++ -> edit -> EOL Conversion -> select unix.
