   What version of PyArrow are you using?
   
   I created this minimal reproducible example, can you run it and check if it works for you?
   
   ```python
   import pandas as pd
   import pyarrow as pa
   import pyarrow.parquet as pq
   
   chunk = pd.DataFrame([True, False, None], columns=['col1'])
   field = pa.field("col1", pa.bool_())
   glue_schema = pa.schema([field])
   
   table = pa.Table.from_pandas(chunk, preserve_index=False, schema=glue_schema)
   
   # Open a Parquet file for writing
   pq_writer = pq.ParquetWriter('example.parquet', 
                                schema = glue_schema,
                                compression='snappy')
   
   # Write CSV chunk to the parquet file
   pq_writer.write_table(table)
   pq_writer.close()
   
   # Read the chunk
   pq.read_table('example.parquet').to_pandas()
   ```
   
   It should create this output:
   
   ```python
   >>> pq.read_table('example.parquet').to_pandas()
       col1
   0   True
   1  False
   2   None
   ```
