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?

Solution

  • 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.
