This test now fails with

Expected: iterable with items [<NestedWithFields(Required$2(0,0),None)>, <NestedWithFields(Required$2(1,1),Some(Optional$2(1)))><NestedWithFields(Required$2(2,2),Some(Optional$2(2)))>, ...] in any order
     but: not matched: <NestedWithFields(Required$2(0,0),Some(Optional$2(0)))>

Tried to debug but it seems it comes from the bigquery session. avro bytes sent tell the optional.int field is set to 0. There is probably an issue with projection in the library.
