Parsing nested elements from JSON response using a postman test script - postman

Question

I'm using the following Postman test script to check and log the status of a POST.
pm.environment.unset("uuid");
var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable("uuid", jsonData.id);
var base = pm.request.url
var url = base + '/status?uuid=' + pm.environment.get("uuid");
var account = pm.request.headers.get("account")
var auth = pm.request.headers.get("Authorization")
pm.test("Status code is 200",
setTimeout(function() {
console.log("Sleeping for 3 seconds before next request.");
pm.sendRequest ( {
url: url,
method: 'GET',
header: {
'account': account,
'Accept': 'application/json',
'Content-Type': 'application/json;charset=UTF-8',
'Authorization': auth
}
},
function (err, res) {
console.log(res.json().messageSummary);
})
},3000)
);
The script is able to make the call and retrieve the messageSummary from the response:
{
"id": "3c99af22-ea07-4f5d-bfe8-74a6074af71e",
"status": "SUCCESS",
"token": null,
"messageSummary": "[2] Records uploaded, please check errors/warnings and try again.",
"data": [
{
"ErrorCode": "-553",
"ErrorMessage": "Error during retrieving service service_id entered"
}
]
}
I'm wanting to also get the nested ErrorMessage, but so far everything I've tried comes back undefined or throws an error.
I assumed console.log(res.json().data[1].ErrorMessage) would work, but, alas, it does not.
UPDATE: arrays start with [0] not [1]...
pm.environment.unset("uuid");
var jsonData = pm.response.json();
pm.environment.set("uuid", jsonData.id);
var base = pm.request.url
var url = base + '/status?uuid=' + pm.environment.get("uuid");
var account = pm.request.headers.get("account")
var auth = pm.request.headers.get("Authorization")
setTimeout(function() {
console.log("Sleeping for 3 seconds before next request.");
pm.sendRequest ( {
url: url,
method: 'GET',
header: {
'account': account,
'Accept': 'application/json',
'Content-Type': 'application/json;charset=UTF-8',
'Authorization': auth
}
},
function (err, res) {
console.log(res.json().messageSummary);
console.log(res.json().data[0].ErrorCode + ': ' + res.json().data[0].ErrorMessage)
})
},3000)

You would need to change the [1] to [0] to fix that reference.
