Adding image to pdf not working when deployed

[0xfourzerofour]

Description

I have a function running in a lambda that will grab a document from s3 and then add an image to the document using the NewImageFromData function along with Creator.Draw

I have tested the function on my local machine and it works like a charm but whenever I upload it to the lambda env and run the code it will not add the image to the input pdf.

example function code (errs removed to read easier)

 	c := creator.New()
	pdfReader, err := model.NewPdfReader(bytes.NewReader(file))
        err = addImageToPdf(c, pdfReader, &body, pageNum, xPos, yPos, scaledWidth)

	buf := new(bytes.Buffer)
	err = c.Write(buf)

	sess := session.Must(session.NewSessionWithOptions(session.Options{
		SharedConfigState: session.SharedConfigEnable,
	}))

	s3conn := s3.New(sess)

	s3PutInput := s3.PutObjectInput{
		Bucket: aws.String(os.Getenv("sign-bucket")),
		Key:    aws.String("local-pdf.pdf"),
		Body:   bytes.NewReader(buf.Bytes()),
	}

	_, err = s3conn.PutObject(&s3PutInput)

func addImageToPdf(c *creator.Creator, pdfReader *model.PdfReader, image *[]byte, pageNum int, xPos, yPos, scaledWidth float64) error {

	// Prepare the image.
	img, err := c.NewImageFromData(*image)
	if err != nil {
		return err
	}

	img.ScaleToWidth(scaledWidth)
	img.SetPos(xPos, yPos)

	if err != nil {
		return err
	}

	numPages, err := pdfReader.GetNumPages()
	if err != nil {
		return err
	}

	// Load the pages.
	for i := 0; i < numPages; i++ {
		page, err := pdfReader.GetPage(i + 1)
		if err != nil {
			return err
		}

		// Add the page.
		err = c.AddPage(page)
		if err != nil {
			return err
		}

		// If the specified page, or -1, apply the image to the page.
		if i+1 == pageNum || pageNum == -1 {
			_ = c.Draw(img)
		}
	}

	return nil
}

I have used the exact same code in the deployed version however it does not work.

I think this may be something to do with the version as my local go version is 1.18 and the deployed version is 1.16
