ENOENT Errors Once ElectronJS Project is Packaged

Question

So I wrote a program using ElectronJS and packaged it via electron-packager. There's a line of code in there that utilizes fs.copyFileSync, which copies an image from the user to an internal folder in the project directory. To get the internal director path I of course use app.getPath() but have also used __dirname (neither work).

In a development environment, everything works and copies fine with no errors what so ever. However, once packaged, no matter what OS it's running on, whenever I try to copy an image from the user to the internal folder I get an ENOENT error.

I assume this is permission based or based on the fact that folder structure changes once packaged? Although I assumed app.getPath() would solve this it has not.

Any help would be much appreciated

EDIT: Here is the line of code doing the copying:

fs.copyFileSync(decodeURIComponent(Object.values(data)[1].substring(7)), path.join(__dirname, 'renderer', 'images', 'empPhotos', String(newEmpID).substring(1) + '.jpeg'), fs.constants.COPYFILE_EXCL, (err) => {
            if (err) throw err;
            e.returnValue = "FAIL";
        });

Here is the full error when ran in packaged format on MacOS (issue persists on all platforms):
