Trying to instantiate chain code on channel

Question

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: API error (404): network network byfn not found

Answer 1

Looking at the error, it seems like there is a blank space between the words "network" and "byfn" whereas it should be one single word separated by an underscore ("network_byfn"). Open your docker-compose.yaml file and change the value of CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE to network_byfn. Let me know if this works.
