How do I convert local .JPG file to Base64 to work with Boto3 and Detect_Text?

Question

Relevant Code:

import boto3
from PIL import Image
import base64

client = boto3.client('rekognition')

filename = r'C:\Users\H-63\Pictures\scantests\Rekognition test.JPG'

with open(filename, 'rb') as image_file:
    image = image_file.read()

image = base64.b64encode(image).decode('UTF-8')

response = client.detect_text(
    Image={'Bytes': image
        })

However, When I run this, I get an error:

An error occurred (InvalidImageFormatException) when calling the DetectText operation: Request has Invalid image format

How do I get my image to be the right format for detect_text? The documentation says it has to be base64 encoding.

I'm not sure why the documentation even mentions base64, but the function requires bytes. So just use:

with open(filename, 'rb') as image_file:
  image = image_file.read()
  client.detect_text(Image={'Bytes': image})
