How to solve Hyperledger Fabric error endorsing chaincode error

+1 vote

I am trying to practice the Hyperledger Fabric tutorial from the Hyperledger Fabric documentation on Ubuntu and I 
executed 

$ ./byfn.sh -m up

and then 

peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

I get the following error:

Error: Error endorsing chaincode: rpc error: code = Unknown desc = chaincode error (status: 500, message: Error installing chaincode code mycc:1.0(chaincode /var/hyperledger/production/chaincodes/mycc.1.0 exists))

How to solve this?

Try to install chaincode with a name that overlaps the name of the currently installed chaincode by byfn.sh

Try something similar to the following code: 

peer chaincode install -n myNewCC -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02


Hope this helps!

You are getting this error because a chaincode name mycc already exists. Try removing that chaincode and then try running this command again. It will work.
