Problem
I'm getting the following error on a fabric-peer: Failed to generate platform-specific docker build: Error returned from build: 1 "can't load package: package chaincodes/simple: no buildable Go source files in /chaincode/input/src/chaincodes/simple.
Context
I'm trying to instantiate a chaincode package after having successfully installed it.
Both the install and instantiate proposals are created by the Fabric NodeJS SDK (fabric-client).
Steps leading up to the problem
- Package a go file using the fabric-client (succeeds)
- Create an install proposal and send it to the peer (succeeds
- Create and instantiate proposal and send it to the peer (fails with above error-message)
Steps taken to solve the problem
I tried to assert how the chaincode container create process works by reading the code.
What I got from it was the following:
- The chaincode is build using the fabric-ccenv image
- It loads a .tar as an Inputstream (The package?)
I tried adding the files to the go-path but I still couldn't get it to work.
What I want to know
- Where does the chaincode building process expect these files to be?
- Why do I need to provide the files when I've previously sent a package of chaincode inside an InstallRequest?
Further information
I'm also getting an error about an MSP being unknown. Something along the lines of: Error: MSP Org1MSP is unkown. This happens during deserialization of the proposal.
Which is weird because I'm 100% that MSP exists. What I'm not certain about is whether I need to add anchor peers to the channel I'm installing and instantiating the chaincode on in order for the MSP to be found.
I thought that happens during channel creation.
Versions
This happens in the following versions:
- 1.0.0
- 1.0.6
Please do not suggest I try version 1.1 because I cannot upgrade easily.
Please advise.
回答1:
Above was caused by an actual unknown MSP.
Double check the profile/profiles in configtx.yaml used for creating the channel and the genesis block for orderers. I had a mismatch between those.
I read a related issue [FAB-7952] in Fabric's issue manager and it made me think something else was going on, instead of an actual unknown MSP.
