For web service Rest API, getting error as

Using 5.3.1, I get the error code in my script, but if I execute the WS from the WebService Object by clicking Test Request, it doesn’t give any indication of the 400/404 error. Instead it looks like nothing was run. The 400/404 error should either give the old popup when tested or display some details in the Response tab.

Getting bad gateway error katalon 6.0.5

Still having this kind problem till this day. I`m using the version 7.7.2 of Katalon Studio. I imported the request from Postman and it works fine there, but in Katalon I get the HTTP error code 404. It is also a simple request with grant_type, client_id and client_secret.
