I have script to do API automation by fetching data from CSV file and comparing JSON response with the data in CSV file in POSTMAN. I have 12 scenarios/ iterations to verify and each scenario sends more than 20 data picking from CSV file and from JSON response compared more than 10 data. Everything is working fine.
Now Security feature implemented in code, so I have to send the request and Automate the script with ID/PWD. So I used NTML authentication with ID and PWD.
When I run the script with runner, initial two iteration gives perfect response and script passed, then from 3rd iteration all script failed and not getting response. In response it says Data unavailable when I checked in postman console it shows below details.

What could be the reason and any solution to solve this.
I got the Postman error message
JSONError: Unexpected token '<' at 1:1<!doctype html>^ today.
I realized that the problem (in my case) was that I tried to access an API that
I had written myself, but forgotten to upload. - Thus, I tried to call an API
that did not exist. (!)
As soon as I uploaded the API, the error went away.
