------------------------------------------------------------------

Hi, we're also experiencing this same bug. We're unable to use R to read a parquet file with a column filled with null. The same parquet file can be read in fine using Python (pandas.read_parquet using 'pyarrow' as the engine).

 

Any thoughts on how to fix this issue or any workarounds?
