Am I missing something with Images

// inside a worker, Hono + oRPC. input.file = File
const fileBuffer = await input.file.arrayBuffer();

const transformedImage = await context.env.IMAGES.input(
    arrayBufferToReadableStream(fileBuffer),
)
    .transform({
        width: 256,
        height: 256,
        fit: "cover",
    })
    .output(input.output ?? { format: "image/avif" });

const fileName = `${Date.now()}.avif`;

const object = await context.env.BUCKET.put(
    fileName,
    await transformedImage.response().arrayBuffer(),
    {
        httpMetadata: {
            contentType: transformedImage.contentType(),
        },
    },
);

return `${context.env.BUCKET_PUBLIC_URL}/${object.key}`;
