If i try to use in the pre-request script btoa() methods i’m getting this error:

There was an error in evaluating the Pre-request Script: TypeError: btoa is not a function

Before the Postman last update it was working!!

We find out issue, I clone POST with body, then change it to GET body was hidden BUT after export collection body was there for GET request. This is the reason.
