POSTMAN - There was an error in evaluating the Pre-request Script:Error: Cannot read properties of undefined (reading 'json')

I am beginning the journey to learn how to use the API for Zoho Sign.

I am getting the following error when I try to use postman.

To walk you through how I am getting this error...

I wanted to start with a simple GET and expand my learning from there.

I downloaded the Postman Sign collection.

Then I went here to get a development token.

I then pasted the token into Postman

Then I send a request to get document list.

And I get this error.

```There was an error in evaluating the Pre-request Script:Error: Cannot read properties of undefined (reading 'json')```

What am I doing wrong here?
