In postman tests, How to assert the response parameter which as special chars in it

[chinna92 (Jagadeesh T)]

I’m using postman tests section to automate the APIs

If the response parameter is something like this "currency": "USD",, then we assert this by pm.expect(jsonResponse.currency, 'USD');

But if the response parameter is something like this "super-card.DCC": "false",, in which key has -, .(dot) in it.
Then asserting like this pm.expect(jsonResponse.postingAttributes.super-card.DCC, false); is not working.

Its failing with ReferenceError: card is not defined

Screenshot for reference:

Can anybody help me here?

dot notation won’t work as the element has a dot in it, so you can use bracket notation instead to target the element. You can mix the two when targetting elements.

console.log(jsonResponse.postingAttributes["super-card.DCC"]);
