Error: t is undefined when using base64-encoded image as background-image

Bug report

Description / Observed Behavior

I try to use a picture as background for OpenGraph images in Next.js though next/og's ImageResponse. Because of limitations when using the Node runtime for SSG, I tried using a base64-encoded image. I then encountered TypeError: a is not iterable. When I went to reproduce the issue on Satori's playground, I got another error: t is undefined.

Expected Behavior

Background should be shown as bellow:

Reproduction

I had to past the URL in a Gist because it's too long and it hit GitHub's body limit 😓
