Review Comment:
FYI, even with this suggested change we still get `Cannot resolve "filter(a,
lambdafunction((x_0 IS NOT NULL), x_0))"` error. The only difference I am
seeing is in `Project` node
Seq.empty
```
[DATATYPE_MISMATCH.UNEXPECTED_INPUT_TYPE] Cannot resolve "filter(a,
lambdafunction((x_0 IS NOT NULL), x_0))" due to data type mismatch: Parameter 1
requires the "ARRAY" type, however "a" has the type "INT".;
'Project [unresolvedalias(array_compact(),
Some(org.apache.spark.sql.Column$$Lambda$1642/1906635841@124eb83d))]
+- Project [value#1 AS a#4]
+- LocalRelation [value#1]
