Unknown MSP DEFAULT error query chaincode

0 votes

I tried deploying the following example :

http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html

It shows me an error when I try running the following command:

peer query -C mychannel -n mycc -c {"Args":["query","a"]} 

The error is stated as:

"failed to deserialize identity, err MSP DEFAULT is unknown".

The query is copied from script.sh, which is called by

./byfn.sh -m up

But it doesn't run directly. Can someone help?

./byfn.sh -m up

After running the above command, Connect to the cli docker image initialized and running by invoking

docker exec -it cli /bin/bash
For peer cli to be able run correctly there is a set of environmental variable you have to provide. Basically you need to point to the endorsing peer and to the MSP configuration, setting the MSP ID as well. If you haven't configured those values, there would be an error.
