Can I provide in clause in json like facts.get('value') in ('a', 'b', 'c', d')

Hi, I am doing a poc to use Easy rules by defining rules in a json file. My question is can I define in condition in json as provided below.

[ { "name": "TestRule", "description": "Test rule", "condition": "facts.get('value') in [9, 10]", "actions": ["System.out.println(\"Passed\");"] } ]

Currently I am getting an exception

java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.Boolean (java.lang.Integer and java.lang.Boolean are in module java.base of loader 'bootstrap') at org.jeasy.rules.mvel.MVELCondition.evaluate(MVELCondition.java:65) at org.jeasy.rules.mvel.MVELRule.evaluate(MVELRule.java:120) at org.jeasy.rules.core.DefaultRulesEngine.doFire(DefaultRulesEngine.java:97) at org.jeasy.rules.core.DefaultRulesEngine.fire(DefaultRulesEngine.java:70) at com.wayfair.my.java.project.service.EasyRylesService.runEasyRulesEngine(EasyRylesService.java:53) at com.wayfair.my.java.project.service.EasyRylesService.main(EasyRylesService.java:31)

Thanks in advance for the help.

That's because you provided illegal JSON data. It has nothing to do with easyRuleEngine. It doesn't need to care about how you store your rules.

[
    {
        "name": "TestRule",
        "description": "Test rule",
        "condition": "facts.get('value') in [9, 10]",
        "actions": [
            {
                "ACTION1": "DO ONE"
            },
            {
                "ACTION2": "DO TWO"
            }
        ]
    }
]
