How to assert JSON not null object

[Materia Confusa]

Must be missing something really easy. Say I have a JSON response like so:

{
    "status_code": 200,
    "response_size": "144",
    "data": null,
    "errors": [
        {
            "message": "Something............"
        }
    ]
}

I need to assert that data is not a null object. There is a notNullValue() but that isn't correct. What am I missing?

TIA

You can indeed use notNullValue(). If you have a service called "x" that returns your JSON you can do like this:

when().

          get("/x").

then().

         body("data", notNullValue());

Ah, I see what I was doing wrong. Seems you can't do it all in one body() call. This will not work:

body("data", notNullValue(), "data.publisher_id", equalTo("whatever"))

Throws:
java.lang.IllegalArgumentException: Cannot get property 'publisher_id' on null object

Hmm I actually think that should work as well. But if data is null then perhaps you can run into that exception.
