I just hit this issue using spark 3.1.1 using Koalas 1.7.0

> I got below error when using from_arrow_type() in pyspark.sql.pandas.types
> {{Unsupported type in conversion from Arrow: null}}
> I noticed NullType exists under pyspark.sql.types so it seems possible to
> convert from pyarrow null to pyspark null type and vice versa.
