Trying to set Janusgraph Docker with Cassandra and ES as backend. When starting with following gremlin-server.yaml configuration it comes up properly and data gets saved in (janusgraph) tables in cassandra.
`host: 0.0.0.0`
`port: 8182`
`scriptEvaluationTimeout: 0`
`channelizer: org.janusgraph.channelizers.JanusGraphWebSocketChannelizer`
`graphManager: org.janusgraph.graphdb.management.JanusGraphManager`
`graphs: {`
` graph: conf/janusgraph-cql-es.properties`
`}`
But when trying to set multiple graphs i.e. attempting to add ConfigurationManagementGraph in gremlin-server.yaml then getting error:
graphs: {
ConfigurationManagementGraph: conf/janusgraph-cql-configurationgraph.properties,
graph: conf/janusgraph-cql-es.properties
}
Error message on docker restart:

I have all dockers process running on same host and configured with ip 127.0.0.1. Need guidance to resolve this issue.
Thanking you in anticipation
