Bug is here in caliper.js

results.thePromise.then( () => {
    // DO NOT EXIT THE PROCESS HERE
    // The event loops of the workers are still running at this point
    // The default exit code is 0 anyway
}).catch((error) => {
    Logger.error(`Error during command execution: ${error}`);
    process.exit(1);
});

results doesn't contain a property called thePromise` when an unknown command is used
