Hi guys,

My application return XML for the request. I send the request as described below and got an error “ParceError at [row,col]:[1,1] Message: Contant is not allowed in prolog” as in the screenshot .

After clicking “OK” the response displayed in the Katalon, see screenshot "afterOKClick.png

Could you please clarify how to avoid this error message?
