Behavior with SQL nulls:

>>> df = session.sql("select array_construct(20, 0, null, 10) as A")
>>> df.select(array_min(df.a).as_("min_a")).collect()
[Row(MIN_A='0')]
>>> df = session.sql("select array_construct() as A")
>>> df.select(array_min(df.a).as_("min_a")).collect()
[Row(MIN_A=None)]
>>> df = session.sql("select array_construct(null, null, null) as A")
>>> df.select(array_min(df.a).as_("min_a")).collect()
[Row(MIN_A=None)]

Behavior with JSON nulls:
