Following the readme ends in failure.

I'm following the steps in the README and when I get to the step to create the ops channel and then deploy the OpsSC chaincodes, I get the following errors: obptools@ochain:~/fabric-opssc/sample-environments/fabric-samples/test-network$ ./network.sh createChannel -c ${OPS_CHANNEL_ID} Creating channel 'ops-channel'.

Any help would be appreciated.

Thank you for your report.

This failure seems to have occurred because the channel_ops chaincode is already installed on peer0.org1 (fabric-samples which OpsSC uses does not consider such case).

This might have happened because of old network environment remaining.

Please try to clean up the network first by using the following commands:

$ cd ${FABRIC_OPSSC}/integration
$ ./teardownDockerEnv.sh

Then, please rerun from this step.

If it still does not work, we need more information and logs. Result of executing docker ps -a command and/or docker logs command may be useful for analyzing the cause.
