  screenshot := robotgo.CaptureScreen(0, 0, screenWidth, screenHeight)
  fileName := fmt.Sprintf("%s_%s_%s_%s.png", subVendor, integrationType, vendorID, ct.Format("15_04_05"))

  // Save the screenshot as a PNG file
  robotgo.SaveBitmap(screenshot, "tmp/"+fileName)
  // defer os.Remove(fileName) // Remove the local screenshot file when done

  file, err := os.Open("tmp/" + fileName)
  if err != nil {
  return fileName, err
  }
  defer file.Close()

  // Upload to S3 bucket using PutObject API call
  sess := session.Must(session.NewSessionWithOptions(session.Options{
  SharedConfigState: session.SharedConfigEnable,
  }))

  svc := s3.New(sess)
  bucketName := os.Getenv("s3Bucket")
  _, err = svc.PutObject(&s3.PutObjectInput{
  Bucket: aws.String(bucketName),
  Key: aws.String("errors/" + fileName),
  Body: file,
  })
  if err != nil {
  return fileName, err
  }

  return fileName, nil
  }
