NextJS body exceed limit when content sent in body is under limit.

        const size = image.size / 1024;
        console.log(size);
        if (size >= 4096) {
          console.log("Error, image to large");
          return;
        }
        const foundText = await image.arrayBuffer();
        console.log("NewSize", foundText.byteLength / 1024);
        const uint = new Uint8Array(foundText);
        console.log("BlogStringw", uint.length / 1024); // Shows the correct size, if I upload a 3mb file it shows its 3000kb.

        upload(uint, false, image.type);
        setImage(null);
        setIsDragging(false);

export const config = { // Config for bodyparser it is working
  api: {
    bodyParser: {
      sizeLimit: "8mb", // Set desired value here
    },
  },
};
