POSTMAN get request error - '400 bad request'

I’m working on ‘Set-up Postman’ as below link,

but it works at my browser (localhost:4000/users) but when I try it at postman desktop app, it showed 400 bad request? If anyone had this experience and solved it, pls let me know how to handle that.

error msg:

SyntaxError: Unexpected token ' in JSON at position 1
   at JSON.parse (<anonymous>) Thanks!
