Cannot send attachment using /message

Thanks for the fun app. I'm fiddling with it for fun and sending text messages works fine but I cannot get images to attach. Here's my python script:

requests.post("http://localhost:3005/message", json={
        "body": {
            "message": "I made this image for you."
        },
         "attachments": [
            {  "mimeType": "image/jpeg", "filePath": "/Users/johan/Downloads/512.jpg" }
        ],
        "recipient": {
            "handle": "REDACTED", # my appleid email, so i'm sending as myself. 
        }
    })

The message shows up and a placeholder for the image, which is marked as Not Delivered after a while.

When trying with a png, I don't even get the preview image icon in the thread, so no luck there either.

I'm figured I'd look in the logs to see if I can find more info, but I don't know where the logs are written to. Any ideas are very welcome!

I think this is due to a permissions issue, can you try sending an image that's in ~/Pictures/ instead?
