> EnumerableUncollect throws NPE when an input has element = ((List) null)
> Example:
> {code}
> SELECT * FROM UNNEST(CAST(null AS INTEGER ARRAY))
> {code}
> In a real situation, it can appear if to use left join. For example:
> {code}
> SELECT ARRAY(SELECT * FROM UNNEST(t.x)) FROM (VALUES(1)) LEFT JOIN (SELECT
> ARRAY[1] as x, 2 as y) t ON t.y = 1
> {code}
