Unable to Start the Netting Entity (Get Started - STEP 5)

[botsbuzz]

The command yarn run-netting-entity -i 60000 fails. Here the terminal log:

yarn run v1.12.3 $ node ./netting-entity/index.js -i 60000 Netting Entity running at http://127.0.0.1:3005/ Utility before Netting: Utility { renewableEnergy: 0, nonRenewableEnergy: 0, households: { '0x0000000000000000000000000000000000000000': { meterDelta: 0, lastUpdate: 1580093881636 } }, transfers: [] } Utility after Netting: Utility { renewableEnergy: 0, nonRenewableEnergy: 0, households: {}, transfers: [] } Computing witness...zokrates compute-witness -a > /dev/null error: The argument '--arguments ...' requires a value but none was supplied
