postman: You need to enable JavaScript to run this app

I've got a new API from the backend team in a new project, when I call the api it returns "you need to enable java...", whereas I had used Postman for another project before... is it related to api, server or something else?

I spent some times pondering on this trepidation.. and then suddenly i realized what was going on..

1. the endpoint does not exist, it could be a misspelling
2. not in the same directory as you expect it to be, try adding or removing "/" at the beginning of the url, particularly if you don't specify the hostname, i.e. fetch('getusername') is different from fetch('/getusername') . . This acceptable in development but NOT when already deployed, it points to different path.
3. the endpoint may be working fine in the Development, but somewhere within in the Production/Staging, it generated some exception.

I don't think that POSTMAN is capable of executing JavaScript in its console. Try doing the same in the web browser it will work (You won't see this error message).
