How to use a worker to download an image into R2

const imageArrayBuffer = await fetch(
    imageUrl,
    {
        method: "GET",
        redirect: "follow",
    },
);
const temp = await imageArrayBuffer.arrayBuffer();

// Cache the image in our CDN
const r2Object = await this.bucket.put(
    `images/${imageRef}`,
    temp,
);

if (!r2Object) {
    throw new Error("Failed to cache image in R2");
}
