java.lang.IllegalArgumentException: invalid start or end for POST web-requests

Hi, guys. Did anyone had this kind of error?

I’m trying to send post request to specific url. It returns this error even if request is completely empty and there are NO ANY arguments. I’ve tried the same via postman app and it works as expected (works well, I mean).

Is it a Katalon error? How I can solve this within Katalon Studio and without using Postman for my requests?

I’m using Katalon Studio Version: 5.7.0 Build: 1 MacOS (Update: same on 5.8.0)

or my mistake?
