401 Unauthorize

Can you please provide your code snippet

I'm new in Postman, here is the code. i tried re-generating token as well but failed too.

URL (https://gorest.co.in) defined as pGorestURL at collection level:
Bearer Token at collection level
request auth setting ( inherit authentication from parent).

{{pGorestURL}}/public/v2/users
var random = Math.random().toString(36).substring(2);

var username = jim+random;
var useremail = jim+random+gmail.com;

pm.environment.set(username, username);
pm.environment.set(useremail, useremail);

{
name:{{username}},
gender:Male,
email:{{useremail}},
status:inactive
}

Please let me know if anything wrong doing.
