 ### Fixed
 
 - Fixed `ValueError` in `Neo4jGraphParquetFormatter` when nodes of the same label have mixed property types (e.g. `str` and `int` for the same property), which caused `pa.Table.from_pylist()` to fail. Mixed-type columns are now coerced to a consistent type before Parquet table creation.
