**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):  
2.8.0

**Describe the issue** :  
I tried this

```auto
POST /_plugins/_ml/models/_upload
{
  "name": "sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2",
  "version": "1.0.1",
  "description": "This is a sentence-transformers model: It maps sentences & paragraphs to a 384 dimensional dense vector space and can be used for tasks like clustering or semantic search.",
  "model_task_type": "TEXT_EMBEDDING",
  "model_format": "TORCH_SCRIPT",
  "model_content_size_in_bytes": 488135181,
  "model_content_hash_value": "a2ae3c4f161bd8e5a99a19ba5589443d33a120bb2bd67aa9da102c8b201f1277",
  "model_config": {
    "model_type": "bert",
    "embedding_dimension": 384,
    "framework_type": "sentence_transformers",
    "all_config": "{\"_name_or_path\":\"old_models/paraphrase-multilingual-MiniLM-L12-v2/0_Transformer\",\"architectures\":[\"BertModel\"],\"attention_probs_dropout_prob\":0.1,\"gradient_checkpointing\":false,\"hidden_act\":\"gelu\",\"hidden_dropout_prob\":0.1,\"hidden_size\":384,\"initializer_range\":0.02,\"intermediate_size\":1536,\"layer_norm_eps\":1e-12,\"max_position_embeddings\":512,\"model_type\":\"bert\",\"num_attention_heads\":12,\"num_hidden_layers\":12,\"pad_token_id\":0,\"position_embedding_type\":\"absolute\",\"transformers_version\":\"4.7.0\",\"type_vocab_size\":2,\"use_cache\":true,\"vocab_size\":250037}"
  },

}

```

got

```auto
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "model group id is null"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "model group id is null"
  },
  "status": 400
}

```

**Configuration** :  
I have been running opensearch cluster locally from neural-search docker compose

You need to register a model group first and use that group id to register a model. Please checkout [this doc](https://github.com/opensearch-project/ml-commons/blob/2.x/docs/model_access_control.md#registering-a-model-group)
