Expand image internal error

I am making a to expand image: https://docs.bria.ai/image-editing/v2-endpoints/image-expansion

My payload:
{
"image": "https://d1e......cloudfront.net/api/.....",
"preserve_alpha": true,
"sync": true,
"aspect_ratio": "16:9"
}

Response:
{"error":{"code":500,"message":"Internal Server Error","details":"normalize() argument 2 must be str, not None"},"request_id":"97a838bb445a4a3296f9921a04c6ea10"}

Is this an error from my end?
Other image editing endpoints are working well.
