| API error (404): network_test not found | Components are at different network | export COMPOSE_PROJECT_NAME=net |
| API error (404): network docker_test not found | Possible mismatch in network mode in docker-compose.yaml or core.yaml | Option 1 Change CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE variable in docker-compose-test-net.yaml file from ${COMPOSE_PROJECT_NAME}_test to docker_test. Verify that the NetworkMode in core.yaml is set to docker_test |
| API error (404): network docker_test not found | docker-compose reading .env file for project name | Option 2 Create a .env file in the test_network folder. Add COMPOSE_PROJECT_NAME=docker in .env file. Add .env file to the docker-compose commands in the network.sh file docker-compose --env-file ./.env |
| Channel cannot be created due to tcp connection error | Conflicting docker images | Check for any old docker images. Get new docker images after deleting old ones |
| FileNotFoundError: Errno 2 No such file or directory. Failed to execute script docker-compose | docker-compose command throws error | Try docker compose instead |
| Failed to create deliver client: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: context deadline exceeded | Possibly applied capabilites in configtx.yaml dont match the fabric binaries |
Ensure the fabric binaries match the capabilites expected for the orderer |
| Unable to give network name in docker-compose | docker-compose 1.28.5 needed | curl -L https://github.com/docker/compose/releases/download/1.28.5/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose |

| Could not assemble transaction: ProposalResponsePayloads do not match proposal response: version:1 response:<status:200 > | Mismatch in the payloads returned by the peers | Check if the same chaincode is installed and instantiated on all peers. The environment variables are set correctly for the peers. The output is same on all peers. |

| Failed constructing descriptor of chaincode when trying to process the transaction | Chaincode name mismatch | The chaincode that's deployed and the chaincode that is being executed via network.getContract should have same name |
| sendPeersProposal: Promise is rejected: Error: chaincode with name chain-code-name already exists | Chaincode was already instantiated on peers | Install new version of the chaincode and then instantiate |
