Test Execute, unable to open the file

hmmm

If You want to work with Project Script files You need to use an absolute path.

You can get path to You to project with this method: aqFileSystem.GetCurrentFolder();

 

let pathToFile = aqFileSystem.GetCurrentFolder();
let writeToFile = aqFile.WriteToTextFile(
  pathToFile + "\\script\\" + fileName + ".js",
  str,
  aqFile.ctUTF8, true
);
