Error on save: index [datahub_rest_index__catalog-assets__objectfolder-even/] already exists

[NiklasBr]

Pimcore 10.5.12, Datahub 1.5.2, CI Hub Bundle 2.0.1, PHP 8.1.15.

When saving a configuration we get the following error:

{
  "error": {
    "root_cause": [
      {
        "type": "resource_already_exists_exception",
        "reason": "index [datahub_rest_index__catalog-assets__objectfolder-even/xOj4qXzsRY-vhcP3z-Y1Sg] already exists",
        "index_uuid": "xOj4qXzsRY-vhcP3z-Y1Sg",
        "index": "datahub_rest_index__catalog-assets__objectfolder-even"
      }
    ],
    "type": "resource_already_exists_exception",
    "reason": "index [datahub_rest_index__catalog-assets__objectfolder-even/xOj4qXzsRY-vhcP3z-Y1Sg] already exists",
    "index_uuid": "xOj4qXzsRY-vhcP3z-Y1Sg",
    "index": "datahub_rest_index__catalog-assets__objectfolder-even"
  },
  "status": 400
}

It looks like the error is thrown in IndexManager::createOrUpdateIndex(string $indexName, array $mapping).

The datahub configuration looks like this:

pimcore_data_hub:
    configurations:
        catalog-assets:
            general:
                active: 'on'
                type: ciHub
                name: catalog-assets

            schema:
                assets:
                    allowOriginalImage: 'on'
                    thumbnails:
                        - galleryThumbnail
                dataObjectClasses:
# long config removed

ES in docker-compose.yaml looks like this:

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.6.2
    container_name: eleasticsearch
    environment:
      - discovery.type=single-node
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - ingest.geoip.downloader.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
      nofile:
        soft: 65536
        hard: 65536
    cap_add:
      - IPC_LOCK
    mem_limit: 1g
    volumes:
      - ./docker/elasticsearch/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      - elasticsearch-data:/usr/share/elasticsearch/data
    ports:
      - "9200:9200"
      - "9300:9300"

The referenced elasticsearch.yml in the above snippet looks like this:

cluster:
  name: "docker-cluster"

network:
  host: 0.0.0.0

action:
    destructive_requires_name: false

xpack:
  security:
    enabled: false
    audit:
      enabled: false
    authc:
      anonymous:
        username: anonymous_user
        roles: role1, role2
        authz_exception: false
      token:
        enabled: true

And finally the simple_rest_adapter.yaml config file looks like this:

simple_rest_adapter:
    index_name_prefix: datahub_rest_index
    es_hosts:
        - '%env(ELASTIC_SEARCH_PROTO)%://%env(ELASTIC_SEARCH_HOST)%:%env(ELASTIC_SEARCH_PORT)%'
