Answer 1

As far as I can tell, this is also the case with Python 3. I'm trying to return a binary data (bytes). It's not working at all.

I also tried to use base-64 encoding and I have had no success.

This is with API Gateway and Proxy Integration.

[update]

I finally realized how to do this. I enabled binary support for type */* and then returned this:

return({
        "isBase64Encoded": True,
        "statusCode": 200,
        "headers": {
                "content-type": "image/jpg",
        },  
        'body':  base64.b64encode(open('image.jpg', 'rb').read()).decode('utf-8')
})
