the line that fails is a call to a post call

8858_TranslationServiceCaller.js:29

var parameters = {stringArray: stringArray.join(","),
        		          locale: localeName};

var response = <http://https.post|https.post>({
          url: suiteletURL,
          body: parameters
      });

I cant see what are those parameters because the main script is locked but locale is something like `EP_en_US`dont know what stringArray is
