Please describe the bug 🐞

CALL spark_catalog.system.rewrite_data_files(
  table => '${DATABASE_NAME}.${TABLE_NAME}',
  options => map(
    'max-concurrent-file-group-rewrites', 500,
    'target-file-size-bytes','536870912',
    'max-file-group-size-bytes','10737418240',
    'rewrite-all', 'true')
);

After using spark_catalog.system.rewrite_data_files to merge iceberg small files, the new parquet generated encountered an unreadable problem When currently executing a query operation . The error message is as follows

 Required field num_values was not found in serialized data!

What's the column of num_values ?

Thanks @wardlican for raising this. Do you happen to know which system produced the Parquet files (Spark, Arrow, etc)?
