JSONPath PHP gives false

Question

I've been using JSONPath in my Codeigniter 3 Project. I want to find the result of an expression.

Now, coming to the issue. The Same expression works on an online json evaluator. But the same expression used during the code results into false.

Here's the expression

$.slots[?((('2035-05-16 08:00' >= @.slot_datetime_from && '2035-05-16 08:00' < @.slot_datetime_to) || ('2035-05-16 12:30' > @.slot_datetime_from && '2035-05-16 12:30' <= @.slot_datetime_to) ) && @.venue_id == '1' && @.court_id == '1')]

I'm using one JSON. Here's the link

Here's the code which I'm using.

$existingEntries = new JsonObject($existingSlotAndCourtEntries);
$result = $existingEntries->{$exp};
