Getting items using where on json column resulting in empty data

As the title says, i'm trying to search by json column, but i get empty collection. You can see that in result, my sql query is correct, but somehow it gives me no data, while same query on my database works as expected. I'm doing something wrong here?

I'm using Lumen 5.7.1 and Mysql 5.7.24

Code:

$logs = Activity::where('properties->id', 4);
$sql = str_replace_array('?', $logs->getBindings(), $logs->toSql());
dd($sql, $logs->get());

Result:

"select * from `activity_log` where `properties`->'$."id"' = 4"
Collection {#133
  #items: []
}
