GraphicsMagick: toBuffer() Stream yields empty buffer (Lambda)

I am trying to create a thumb from a pdf file in a lambda, but when I create the image I get the following error:

Error: stream throws an empty buffer.

I have already increased to 300mb of lambda memory and it doesn't work.

const gm = require("gm").subClass({ imageMagick: true });
const fs = require("fs");

const params = {
  Bucket: sourceBucket,
  Key: originalNameImg,
};

const pdf = await s3.getObject(params).promise();

temp_file = mktemp.createFileSync(`/tmp/XXXXXX.pdf`);
fs.writeFileSync(temp_file, pdf.Body);
image = gm(temp_file + "[0]");

image.resize("400", "400").toBuffer("jpg", function(err, buffer) {
  if (err) {
    reject(err);
    return;
  } else {
    resolve();
  }
});

The nodejs version I am using is: Node.js 14.x

you should install gm package that convert images in AWS AMI.

In latest AWI doesn't have the package.
