Managed Data Designer - validation failed - service version mismatch?

[webmaxru]

Hello!

I try to run this notebook:
https://github.com/NVIDIA/GenerativeAIExamples/blob/main/nemo/NeMo-Data-Designer/managed-service-tutorials/getting-started/1-the-basics.ipynb

All works and validates OK until I call managed service itself here
preview = data_designer_client.preview(config_builder)

Then it raises:

DataDesignerConfigValidationError         Traceback (most recent call last)
...
raise DataDesignerConfigValidationError(f"‼️ Config validation failed!\n{e}") from None
     30     else:
     31         raise DataDesignerClientError(f"‼️ Something went wrong!\n{e}") from None

DataDesignerConfigValidationError: ‼️ Config validation failed!
Error code: 422 - {'detail': [{'type': 'missing', 'loc': ['body', 'config', 'columns', 0, 'function-after[assert_expression_valid_jinja(), ExpressionColumnConfig]', 'expr'], 'msg': 'Field required', 'input': {'name': 'product_category', 'drop': False, 'column_type': 'sampler', 'sampler_type': 'category', 'params': {'values': ['Electronics', 'Clothing', 'Home & Kitchen', 'Books', 'Home Office'], 'weights': None, 'sampler_type': 'category'}, 'conditional_params': {}, 'convert_to': None}}, {'type': 'extra_forbidden', 'loc': ['body', 'config', 'columns', 0, 'function-after[assert_expression_valid_jinja(), ExpressionColumnConfig]', 'column_type'], 'msg': 'Extra inputs are not permitted', 'input': 'sampler'}, {'type': 'extra_forbidden', 'loc': ['body', 'config', 'columns', 0, 'function-after[assert_expression_valid_jinja(), ExpressionColumnConfig]', 'sampler_type'], 'msg': 'Extra inputs are not permitted', 'input': 'category'}, {'type': 'extra_forbidden', 'loc': ['body', 'config', 'columns', 0, 'function-after[assert_expression_valid_jinja(), ExpressionColumnConfig]', 'params'], 'msg': 'Extra inputs are not permitted',

Seems like total mismatch of what was sent and what is expected. Could it be client/server version mismatch? I use nemo-microservices v1.5.0
