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
