Docker yaml authentication settings (gremlinserver.authentication) question

Does anyone have any experience setting up authentication on Docker by using the supplied .yaml file? I'm having trouble passingin a map to properly set one of the options: gremlinserver.authentication.config. Additional info, but not related to the my main problem: I have a file with the contents of username/password pairs which follow the schema: username:password (sha256) This file is located within the docker instance at: /etc/opt/janusgraph/janusgraph-credentials-server.properties However, gremlin server expects credentialsDb as a map and docker wants a string. Therefore I seem unable to configure this property. Here are the relevant parts of my docker .yaml file:

services:
  janusgraph:
    image: docker.io/janusgraph/janusgraph:latest
    restart: "on-failure"
    container_name: janusgraph-server-1
    environment:
      JANUS_PROPS_TEMPLATE: cql
      janusgraph.storage.hostname: 192.168.1.44
      janusgraph.storage.port: 9042
      janusgraph.storage.username: cassandra
      janusgraph.storage.password: cassandra
      janusgraph.query.batch.enabled: true
      janusgraph.query.batch.limited: false
      janusgraph.index.search.elasticsearch.interface: REST_CLIENT
      gremlinserver.evaluationTimeout: 180000
      gremlinserver.authentication.authenticator: org.apache.tinkerpop.gremlin.server.auth.SimpleAuthenticator
      gremlinserver.authentication.config: {"credentialsDb": "/etc/opt/janusgraph/janusgraph-credentials-server.properties"} # <--- Source of problem
    ports:
      - "8182:8182"
    networks:

    healthcheck:
      test: ["CMD", "bin/gremlin.sh", "-e", "scripts/remote-connect.groovy"]
      interval: 10s
      timeout: 30s
      retries: 3
    volumes:
      - /home/user/janusgraph-credentials-server.properties:/etc/opt/janusgraph/janusgraph-credentials-server.properties:ro

Dynamic select within query not working.

Any insights or help would be greatly appreciated. I have to pass a list of lists in the format below. Hundreds of them which is why I'm trying to iterate in a single query. Please explain why accessing element 0 within the row data works here: g.inject([['2011-12-01', 3873], ['2023-12-02', 3946], ['2023-12-03', 3997]]). unfold().as('row'). coalesce( select('row').limit(local, 1).unfold() ) But nesting the select within the query to return a matching Vertex does not: g.inject([['2011-12-01', 3873], ['2023-12-02', 3946], ['2023-12-03', 3997]]). unfold().as('row'). coalesce( __.V().hasLabel('UsdValue').has('date', select('row').limit(local, 1).unfold()) ) Ultimately trying to create an if/then exists query but I can't get it to even match.
