Bug report

When satori’s .addFonts method is called, it calls opentype which (in a Next.js app) throws the following error

error - TypeError: Cannot read properties of undefined (reading '259')

Description / Observed Behavior

Could not load a variable font

Expected Behavior

The font loads

Reproduction

const font = fetch(
	new URL(
		'path/to/GeneralSans-Variable.ttf',
		import.meta.url,
	),
).then(async res => res.arrayBuffer());

// Then load with:
const options = {
	fonts: [
		{
			name: "General Sans",
			data: await font,
			style: "normal",
		},
	],
};

Originally was going to report this issue in shuding/opentype.js, but the repo has issues disabled, so was not sure if it was more appropriate to go in https://github.com/opentypejs/opentype.js or here
