Not working with minecraft version 1.18.1

[DevanshRathi1]

Package version: 2.1.0
Node version: 16.13.0

I am trying to read a .mca file that was made by minecraft version 1.18.1.

This is the code that produced the issue (it is the same as the example in the README):

import fs from "fs/promises";
import nbt from "prismarine-nbt";

async function test() {
    const buffer = await fs.readFile(`${directory}/r.0.0.mca`);
    const { parsed, type } = await nbt.parse(buffer);
    console.log("JSON serialized", JSON.stringify(parsed, null, 2));
    fs.createWriteStream("file.nbt").write(nbt.writeUncompressed(parsed, type)); // Write it back
}

test();

Error:

undefined:32
        if (c === '\0') throw new Error('unexpected tag end')
                              ^
