Newman error: “identifier has already been declared at test-script”

[coreydev42]

Cross posting with the Postman forum.

I am trying out newman (version 6.2.1) on my local computer using an exported collection and environment. I am running the test on a single folder in my collection.

The test runs but I get the following error for the two requests: Identifier 'responseBody' has already been declared at test-script.

My post-response test script is defined at the collection folder level. At the top of the script I have: const responseBody = pm.response.json(); and I do not redeclare that variable in the script. I only use that variable to run tests such as pm.expect(responseBody)....

I can run these same tests using the Postman CLI and I do not get this error.

This is my first time using newman. What am I missing?

Thanks.
