Actual behavior

Updating Dataset name with Empty String Returns Success

Expected behavior

Empty name values should either be rejected

Steps to reproduce

1. Send a PUT request to update dataset name with an empty string:

response = requests.put(f'http://127.0.0.1:9380/api/v1/datasets/{dataset_id}', json={"name": ""})

2. The API returns {'code': 0}, indicating success.
3. Query the dataset via the list API:

{
    "code": 0,
    "data": [
        {
            "name": "",  // Empty string persists
            // ...other fields
        }
    ]
}
