Query doesn't return expected results

[fredmajor]

My query is:

select expand(outE('isInvited')[reacted=false].inV()[planned_for > sysdate()] ) from #89:0

When I run it in OrientDB Studio, it returns expected results. When I run it with client.query(my_query_here) it returns nothing. However when I remove the second condition from the query, the client also returns results. (with the test data I use the second condition is always true, so this makes me believe that's rather a parsing/internal pyorient issue) Working query:

select expand(outE('isInvited')[reacted=false].inV() ) from #89:0

pyorient==1.5.5 orientdb==3.0.18-tp3 (docker)

Any help super appreciated.
