Collection variable as a JSON object is not working in newman

Ask the Experts and Postman Tips

I am working on a test script where i am using collection variables to for storing tokens and use it in subsequent calls. Now instead of single variable I used JSON object to make sure one type of data stores in one object. It is working fine in collection Runner. However , in newman it is showing undefined. is new newman unable to handle json object as a variable.
here are the screenshot.
pre-requisite of call 1:

set value in test of call 1

now accessing it in next call like

this is working fine in runner. why it is not working in newman?

Hey @sanu1991,

Could you post the actual code snippets rather than images of them, please? It would make things easier for others to work through it locally. :slight_smile:

HI @danny-dainton, sorry for my late reply. i was trying from my end. i have taken a small example to simulate the same as i cannot share the actual api as it is private business data and i do not have permission.
when i run the coll using postman runner it is working fine. However, the newman unable to parse the json object which i defined in the pre-requisite of the first call.
I am unable to attach the file.

Having a similar issue within newman, you guys had any luck yet?

Collection runner does exactly what it needs to, but as soon as I do the cli run via newman I get 404 responses, which show that something isn’t being passed along correctly (I expect a 204.) Is there a way to get the logs for the newman run to troubleshoot it a bit more diligently?

@kakkiesbarr Not yet. I raised the same issue with Postman github issues.

they marked it as a bug. but given a workaroud. i did not try it as i proceed with single variable.

if you try this let me know does this work or not.

I managed to sort my issue out. Made sure I was resetting the variables before the run, and also saw that I wasn’t adding a header which was required, so unfortunately it seems a little different to your issue.

Best of luck!
