Problem with JSON serialization of rule result

[serban-petrescu]

Summary:

I have an issue when serializing the rule result, namely the conditions inside this result.

Version

2.0.0

Example code

  let engine = new Engine();
  engine.addRule({
    "priority": 4,
    "event": {
      "type": "something"
    },
    "conditions": {
      "any": [{
        "fact": "data",
        "path": ".age",
        "operator": "lessThan",
        "value": 18
      }]
    }
  });
  engine.on("success", (event: any, almanac: any, result: any) => {
    console.log(JSON.stringify(result))
  })
  engine.run({
    data: {
      age: 16
    }
  });

The console will show:

{
	"conditions": "{\"priority\":1,\"any\":[\"{\\\"operator\\\":\\\"lessThan\\\",\\\"value\\\":18,\\\"fact\\\":\\\"data\\\",\\\"path\\\":\\\".age\\\"}\"]}",
	"event": {
		"type": "something"
	},
	"priority": 4,
	"result": true
}

If I look into the debugger it looks fine:

Cause

I did not really dig into this, but based solely on the debugger contents, I guess you "reused" the Condition class for the rule results (at least of the conditions inside it). The custom serialization of this class is most likely causing the issue. IMO, you should make a different "class" for the rule results (condition) object.

Thanks for the detailed bug report @serban-petrescu

I have some time available this week and will get a fix put together.

This is identical to the problem I've been having over in issue #42.

@serban-petrescu please re-open if 2.0.1 does not fix the issue.
