Answers for "actual: java.lang.classcastexception: class java.lang.long cannot be cast to class clojure.lang.ifn (java.lang.long is in module java.base of loader 'bootstrap'; clojure.lang.ifn is in unnamed module of loader 'app')"

class java.lang.Integer cannot be cast to class java.lang.Long (java.lang.Integer and java.lang.Long are in module java.base of loader 'bootstrap')

// on my case, instead of casting I did:

Long variable = Long.valueOf(variable.get("Attribute").toString());
