It works with ArangoDB Queries UI, but not withtriagens/arangodb v3.6.0.

I am using the following versions:

• php v7.4.26
• arangodb v3.9
• triagens/arangodb v3.6.0

$query = '    FOR c in cars        LET carSeats = (            FOR s in c.seats            RETURN s        )    RETURN carSeats';$response = DB::statement($query, []);

Callstack:
