Error Input file contains unsupported image format

Hi I'm getting "Error Input file contains unsupported image format" despite (as far as I can tell) setting everything up correctly. Here's the full output:

This is saveas_file_name: public/img/qrCodes/Fancy-Tournament-2022.png
saveas_file_name instanceof String: true
All PNG parameters
Made new QR
Saving QR as: init_non_logo_qr.png
Output: PNG
SaveAs: public/img/qrCodes/Fancy-Tournament-2022.png
Error Input file contains unsupported image format

Based on this code:

async function generateQRcode(event, next) {
  const data = `${event.slug}`;
  QRLogo.generateQRWithLogo(
    data,
    "public/img/logo.png",
    {
      color: {
        dark: "#98191e", // Red dots
        light: "#FFFFFF", // Transparent background
      },
    },
    "PNG",
    `public/img/qrCodes/${event.slug}.png`,
    function (err) {
      if (err) {
        next(new AppError("There was an error creating your QR code.", 400));
      } else {
      }
    }
  );
}
