Batch add_reference() error while links to other class objects property.

We are trying to achieve some class object property reference links to other class objects property in order to reduce process time for the vectorization and memory. But We are facing issue with below error when calling to batch.add_reference() error as
{'error': [{'message': "ref batch: write inverted batch: write additions: no bucket for prop 'section_content__meta_count' found"}]}
