   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   Getting this exception when trying to load next batch while reading a parquet file.
   The parsing works if the batch size is big enough to process all the parquet contents in one shot. But if I try to give a smaller batch size , the code breaks giving the below exception
   
   java.lang.IllegalArgumentException: should have as many children as in the schema: found 0 expected 8
