age: Query resulting in error: cannot cast agtype integer to type boolean

Hello again (this might happen a lot).

I’m getting the following error when trying to run the below query: cannot cast agtype integer to type boolean (in NodeJS, using pg library):

    SELECT * FROM ag_catalog.cypher('minmail', $$      
    MATCH (u:User {_id: $userId})-[:has]->(p:Profile)
    WHERE p.deleted IS NULL
    RETURN p
    $$, $1) as (p ag_catalog.agtype);

Params:

 '{"userId":"e4510317-67dc-4002-b28d-347699c8f8ca"}' 

Any clue as to what I might be doing wrong?
