[BUG] Opensearch Register ML model error

[samuelfabrizi97]

What is the bug?
Cannot register a ML model on Opensearch local Docker Container.

Exception raised: Cannot invoke "java.lang.Boolean.booleanValue()" because "doesVersionCreateModelGroup" is null

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Update ML cluster settings

PUT _cluster/settings
{
  "persistent": {
    "plugins": {
      "ml_commons": {
        "only_run_on_ml_node": "false",
        "model_access_control_enabled": "true",
        "native_memory_threshold": "100"
      }
    }
  }
}

POST {{Host}}/_plugins/_ml/models/_register
{
  "name": "huggingface/sentence-transformers/all-distilroberta-v1",
  "version": "1.0.1",
  "model_format": "TORCH_SCRIPT"
}

4. GET /_plugins/_ml/tasks/<task_id>

{
  "task_type": "REGISTER_MODEL",
  "function_name": "TEXT_EMBEDDING",
  "state": "FAILED",
  "worker_node": [
    "lhpVlHIjTtq20jNo-wrxjw"
  ],
  "create_time": 1719575940542,
  "last_update_time": 1719575951383,
  "error": """Cannot invoke "java.lang.Boolean.booleanValue()" because "doesVersionCreateModelGroup" is null""",
  "is_async": true
}

What is the expected behavior?
The ML model is registered as specified in the tutorial, by receiving the following message

{
  "model_id":<model id>",
  "task_type": "REGISTER_MODEL",
  "function_name": "TEXT_EMBEDDING",
  "state": "COMPLETED",
  "worker_node": [
    "4p6FVOmJRtu3wehDD74hzQ"
  ],
  "create_time": 1694358489722,
  "last_update_time": 1694358499139,
  "is_async": true
}

I tried with the latest docker image (2.15.0) but faced the same issue.
