I have a program in Go which automatically generates a channel configuration block. If I do it manually using a terminal it generates a block successfully as shown below:

export CORE_PEER_ADDRESS=peer0.debutinfotech.com:7051

export CORE_PEER_LOCALMSPID=debutinfotechMSP

export CORE_PEER_MSPCONFIGPATH=/home/akshay/go/src/ConfigTool/Go/network/crypto-config/peerOrganizations/debutinfotech.com/users/Admin@debutinfotech.com/msp

export FABRIC_CFG_PATH=/home/akshay/.fabdep/config

peer channel create -o orderer0.example.com:7050 -f network/channel-artifacts/mychannel.tx -c mychannel

2018-11-19 16:28:16.162 IST [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized

2018-11-19 16:28:16.205 IST [cli/common] readBlock -> INFO 002 Got status: &{NOT_FOUND}

2018-11-19 16:28:16.205 IST [channelCmd] InitCmdFactory -> INFO 003 Endorser and orderer connections initialized

2018-11-19 16:28:16.413 IST [cli/common] readBlock -> INFO 004 Received block: 0

and I can see the mychannel.block in the directory.

But When I do the same thing using a Go Program. It throws an error as shown below:

2018-11-19 16:22:42.639 IST [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized

2018-11-19 16:22:42.644 IST [common/tools/configtxgen/localconfig] Load -> CRIT 002 Error reading configuration:  Unsupported Config Type ""

The source code of the program is shown below:

dir := utils.GetRootDir()



        os.Setenv("CORE_PEER_MSPCONFIGPATH", *peerOrg.UserDir+"/Admin@"+peerOrg.OrgDomain+"/msp")

        os.Setenv("CORE_PEER_LOCALMSPID", peerOrg.MSPID)

        os.Setenv("CORE_PEER_ADDRESS", "peer0."+peerOrg.OrgDomain+":7051")

        os.Setenv("FABRIC_CFG_PATH", os.ExpandEnv("$HOME")+"/.fabdep/config")

        command := exec.Command("peer", "channel", "create", "-o", "orderer0."+ordererOrg.OrgDomain+":7050", "-c", channel.Name, "--outputBlock", dir+"/network/"+channel.Name+".block")

        command.Env = os.Environ()



        result, err := command.CombinedOutput()

I have set path of FABRIC_CFG_PATH same as I did in terminal but still I have no idea what is wrong in this.

Any suggestion/comment would be really appreciated.

The CORE_PEER_MSPCONFIGPATH was not correct. Setting up a correct path fixed my issue
