TypeError: cannot convert 'int' object to bytes

I had an error when trying to open a parquet file:

Traceback (most recent call last):

I got a similar error and determined it was choking on a column of type FIXED_LEN_BYTE_ARRAY. I was able to work around this by excluding the column.

Traceback (most recent call last):
