Creating assertion to "numeric" object

@lunar-module-meteor3 Welcome to the Community :partying_face:

Yes, I feel you… You need to think of using a bracket notation to access the elements instead of dot notation.

You can see the similar thread here to learn more about it.

In your case it should be something like,

pm.test("Value is as expected", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData['8888'][0]['name']).to.eql("Jerzy");
    pm.expect(jsonData['8888'][0]['Id']).to.eql(10);
});

If this is just a subset of response, please update the path to reach the elements! I hope this is helpful :blush:
