I can't get Rubban to create index patterns

[sclarke81]

Hi, I was wondering if you could help me with where I'm going wrong. I'm using elastdocker 3.2.0 with version 8.5.2. I thought Rubban sounded really useful and have been trying to set it up but it's not creating index patterns for me. I have indexes like:

logstash-dev-2022-12-09 
logstash-dev-2022-12-12 
logstash-test-2022-12-09 

My docker-compose.tools.yml is:

version: '3.5'

services:
  rubban:
    image: sherifabdlnaby/rubban:latest
    restart: unless-stopped
    environment:
      RUBBAN_KIBANA_HOST: "https://${KIBANA_HOST}:${KIBANA_PORT}"
      RUBBAN_KIBANA_USER: ${ELASTIC_USERNAME}
      RUBBAN_KIBANA_PASSWORD: ${ELASTIC_PASSWORD}
      RUBBAN_REFRESHINDEXPATTERN_ENABLED: 'true'
      RUBBAN_REFRESHINDEXPATTERN_SCHEDULE: '*/5 * * * *'
      RUBBAN_REFRESHINDEXPATTERN_PATTERNS: '*'
      RUBBAN_AUTOINDEXPATTERN_ENABLED: 'true'
      RUBBAN_AUTOINDEXPATTERN_SCHEDULE: '*/1 * * * *'
      RUBBAN_AUTOINDEXPATTERN_GENERALPATTERNS: '[{"pattern":"logstash-*","timeFieldName":"@timestamp"}]'

I've tried various patterns logstash-*, logstash-?-* and logstash-*-?. From the logs it looks like Rubban is running successfully, but it always just says "Successfully created 0 Index Patterns.".
