My bad, I should’ve gave you this other version. Since it’s a JXA script you have to either run it via osascript in Terminal or, as I did in the script below, wrap it in a run script call so that it works in Script Debugger:
set JXAScript to "webTarget = 'https://www.macscripter.net';
outputLocation = '~/Desktop';
outputDimensions = { width: 1680, height: 1050 };

run script JXAScript in "JavaScript"
This script is functionally very similar to the earlier one, but I cleaned it up a bit and made it export a PDF.
