JanusGraph fails due to ConfigurationManagementGraphNotEnabledException

When querying JanusGraph from the app, I get the following error:

org.janusgraph.graphdb.management.utils.ConfigurationManagementGraphNotEnabledException: Please add a key named "ConfigurationManagementGraph" to the "graphs" property in your YAML file and restart the server to be able to use the functionality of the ConfigurationManagementGraph class.

Using compose JanusGraph service (version 0.3.1)
