Unable to get a key value called properties "properties": "Value" Groovy

Question

I'm making API requests to a service which returns a JSON object within the body.

I can't seem to get the value of a key called "properties" within groovy.

Everytime I call obj.properties i get the following back

{
  "class": "org.json.JSONObject"
}

but if I call just the obj I get the expected JSON object

{
  "dummy1": ,
  "dummy2": false,
  "dummy3": etsad,
  "dummy4": asdfw,
  "dummy5": qweqwe,
  "dummy6": 123123,
  "properties": {
    "country": UK,
   }
}

Likewise if I obj.dummy2 i get false it's only when I obj.properties do I get the above mentioned response

Your json is incorrect format. Use online editors to verify your json: https://jsoneditoronline.org/ — Hossein Amerkashi, Jun 12 '19 at 16:47

Notice groovy have a special handling for Object's properties, for example for number:

def y = 25
print y.properties

It will print [class:class java.lang.Integer]

So it's part of basic groovy object

As @daggett comment, you can use

  obj.get('properties')

Check out this answer here on how to access the properties of objects.

The reason obj.properties isn't working is most likely due to the fact that every object will have properties, and in your case obj.properties is getting the properties of the JSON object and not the value associated with the key.

Instead of obj.properties, consider obj['properties']
