extracting the json value through json path extractor in jmeter

Question

I am using JSON path extractor with Jmeter.

I need to extract 36735928 or 37851136 which is inside CURRENT. Tried with but no success.

$.payload.reservationLists.CURRENT.[0]

Any suggestion of how to get those values. I don't want to use Regular expression extractor. Is it possible to get the value of the below JSON.

JSON response as below

{
"payload": {
            "userName": {
                        "firstName": "Peter",
                         "lastName": "Pan"
                         },

Answer 1

NOTE: the json posted is broken, it is (at least) missing the last } if the "PAST" element is really to be placed inside the "CURRENT" element

That said, the question is not really clear: you could get the element you want by index with the following expression:

$.payload.reservationLists.CURRENT[36735928]

if you know the name of the element you are trying to retrieve. If this is not what you meant, could you please elaborate on that?

Thank you, bye
