Deployment error

[mcnckc]

I'm trying to deploy contract following provided example

I installed ton.js with yarn add @ton/ton @ton/crypto @ton/core buffer.

Running

import { Cell } from 'ton';

const vanityCode = Cell.fromBoc(
  Buffer.from('te6ccgEBAgEAMgABFP8A9KQT9LzyyAsBAEbT7UTQddch+kCDB9ch0QLQ0wMx+kAwWMcF8ojU1NEB+wTtVA==')
)[0];

with node main.js

results in error:

node_modules\ton-core\dist\boc\cell\serialization.js:160
        throw Error('Invalid magic');
              ^

Error: Invalid magic
    at parseBoc (node_modules\ton-core\dist\boc\cell\serialization.js:160:15)
    at deserializeBoc (node_modules\ton-core\dist\boc\cell\serialization.js:168:15)
    at Cell.fromBoc (node_modules\ton-core\dist\boc\Cell.js:34:51)
    at main.js:3:25

Node.js version: v20.17.0
Yarn version: 1.22.22

How could this be fixed, or how else to achieve succesful deployment?
