Postman collection doesn't run properly

Hello

I have written a request in Postman that runs fine manually when I run it as well as when I run the schedule manually. However when it runs at the scheduled time, it does not work correctly and even the logs are confusing. I have a delay in my test script that isn’t being honored as well.

In the body, I send in the id of my NetSuite saved search that I am querying and in the pre-request script it is authenticating against NetSuite. Here is the pre-request script logic:

const cyptojs = require('crypto-js');

let tokenClientIDStr = 'prod_ns_token_client_id';
let tokenClientSecretStr = 'prod_ns_token_client_secret';
let tokenIDStr = 'PROD_NS_TOKEN_ID';
let tokenSecretStr = 'PROD_NS_TOKEN_SECRET';
let acctIDStr = 'PROD_NS_ACCOUNT_ID';
let ns_acct_url_id = "7936739";
let custom_search_script_id = "1001";
let custom_search_col_script_id = "1002";

pm.environment.set("ns_acct_url_id", ns_acct_url_id);

}

// parse request.params

    if(url_query_string_object[key] == "%7B%7Bcustom_search_script_id%7D%7D") {

}

Here is the code from the test script:

var delayBetweenRequests = 1000; // 1 second delay

// Function to send requests with delays
function sendRequestsWithDelay(requests, delay) {

            index++;

            pm.sendRequest(request, function (err, response) {
                if (err) {
                    console.error('Error:', err);
                } else {

First of all, thank you for your post. Based on my apprehension you performed manual runs through the runner. You are confronted to issues whilst running the same collection through the monitor. There is a difference between the API response validation which involves the response time between the monitor and the runner. You may not appropriately visualize the results on the monitor dashboard. I would like to examine and investigate your collection.

Is there a way to share a public link of your your workspace? Or an export of your collection and your environment ? I will be happy to help.

Sorry for the delay, it will let me share the collection file here

Thanks

I believe collections and environments can’t be shared. May you provide me a link to your public workspace I will be happy to assist.

Hello again

I apologize, I do not believe I can share my environment as this is a business solution and we have security practices in place but I could share the collection. Unfortunately, you would need access tokens to NetSuite and Zoho so I think I will just mark this one closed as I have found that Postman Flows accomplish what I need anyway.

Thank you so much for your reply and have a great day!
