cannot add image to pdf : unknown image format.

[78raoul78]

I get the following error when I try to add a local image to my pdf document :

➜  sandbox npx ts-node ./src/main.ts
/Users/user/payfit/sandbox/node_modules/pdfkit/lib/image.js:34
      throw new Error('Unknown image format.');
            ^

This is my code :

import { createWriteStream } from "fs";
import PDFDocument from "pdfkit";

export const convertImageToPdf = (fileName: string) => {
  const convertedFileName = fileName.endsWith(".pdf")
    ? fileName
    : `${fileName}.pdf`;

  const doc = new PDFDocument({ size: "A4" });
  const { width, height } = doc.page;

  const stream = doc.pipe(createWriteStream(convertedFileName));

  doc.image(fileName, 0, 0, { fit: [width, height] });
  doc.end();
  return new Promise((resolve) => stream.on("finish", resolve));
};

async function main() {
  await convertImageToPdf("IMG_1473.jpg");
}

main();

This is the picture I'm using
