Attempt to convert but get an error "Couldn't initialise file."

[apiwatCMD]

So I am working on some PDF file that comes from Scanner. When I tried to convert it, the error occur

/Users/cmd/Documents/Learn/JS/node-typescript/node_modules/gm/lib/command.js:318
          err = new Error('Command failed: ' + stderr);
                ^
Error: Command failed:    **** Error: Couldn't initialise file.
               Output may be incorrect.

Requested FirstPage is greater than the number of pages in the file: 0
   No pages will be processed (FirstPage > LastPage).
gm convert: Postscript delegate failed (/var/folders/8z/d_ldprrj3116777hgkwkyp_w0000gn/T/gmLOn7Iw).

Do you know how to fix this? It works pretty fine when it comes to typical PDF except one from Scanner. Or do I need to config my app more.

Here's my code below, Thanks.

import fs from "fs";
import { fromBuffer } from "pdf2pic";

const convertPDFToJpeg = async (file: Buffer, page: number) => {
  await fromBuffer(file, {
    quality: 100,
    format: "jpeg",
    saveFilename: "untitled",
    savePath: ".",
    density: 300,
    preserveAspectRatio: true,
  })(page, { responseType: "image" });
};

const handleTestReproduce = async () => {
  const file = fs.readFileSync("src/test-broken-file.pdf");
  await convertPDFToJpeg(file, 1);
};

handleTestReproduce();

Also, I am deeply apologize for that I couldn't give an example of PDF File because I cannot reproduce myself. Most of the case come from users upload their file and it should keep the content as sensitive info. All I can give you is an example of PDF data inside (which I am not an expertise in this PDF thing).

Here's an example of "test-broken-file.pdf"

from the looks of it, it seems that the pdf is corrupted or something. Have you checked if there's an option to modify the pdf output of the scanner?
