Sample market maker not starting - Endpoint was: GET order: null

[ken4ward]

This is my first time trying to start this sample market maker. It gives this error after issuing this command - marketmaker ['XBTUSD']. What can I do?

Importing symbol settings for XBTUSD...
Unable to find settings-XBTUSD.py.
