Trezor generated xPub - 'Invalid network version'

Hi. So I am trying to generate HD addresses from xPub that is generated inside the Trezor.

const network = bitcoin.networks.mainnet;
const xpub = 'ypub6XTWVFLfqkFYarn9NArqtBLziffJttqf1Utaur3sTbTGtgfNaTzkGcRpFgiiieBjQ6rV1rJ7iJ9r9oXGpPXZpkq71yfss2mrKLaauxhjXD4';
const node = bitcoin.HDNode.fromBase58(xpub, network).neutered();
const address = node.derive(0).derive(0).getAddress();

console.log('address', address);

# node index.js 
/vagrant/btc-js/node_modules/bitcoinjs-lib/src/hdnode.js:78
    version !== network.bip32.public) throw new Error('Invalid network version')

Any clues why? It does work with const xpub = 'xpub661MyMwAqRbcG4PQrRAT3N2uxTkXWeRq5kpjyDvStBQP7eW65Lu5rZ3MLoBZJQuZFS9FC7mZZEcgxFZxccRdnqSxopraUB6wVjTqp8ZsS4H'

var bjs = require('bitcoinjs-lib')
var b58 = require('bs58check')

// this function takes ypub and turns into xpub
function ypubToXpub(ypub) {
  var data = b58.decode(ypub)
  data = data.slice(4)
  data = Buffer.concat([Buffer.from('0488b21e','hex'), data])
  return b58.encode(data)
}

// this function takes an HDNode, and turns the pubkey of that node into a Segwit P2SH address
function nodeToP2shSegwitAddress(hdNode) {
  var pubkeyBuf = hdNode.keyPair.getPublicKeyBuffer()
  var hash = bjs.crypto.hash160(pubkeyBuf)
  var redeemScript = bjs.script.witnessPubKeyHash.output.encode(hash)
  var hash2 = bjs.crypto.hash160(redeemScript)
  var scriptPubkey = bjs.script.scriptHash.output.encode(hash2)
  return bjs.address.fromOutputScript(scriptPubkey)
}

// convert ypub string into xpub string
var xpub = ypubToXpub('ypub6XTWVFLfqkFYarn9NArqtBLziffJttqf1Utaur3sTbTGtgfNaTzkGcRpFgiiieBjQ6rV1rJ7iJ9r9oXGpPXZpkq71yfss2mrKLaauxhjXD4')

// grab the HDNode object from the xpub
var hdNode = bjs.HDNode.fromBase58(xpub)

// generate as usual, but instead of getAddress, feed into above function
var address = nodeToP2shSegwitAddress(hdNode.derive(0).derive(0))

You can basically do the same thing as above. Slightly modified.

var bjs = require('bitcoinjs-lib')
var b58 = require('bs58check')

// this function takes zpub and turns into xpub
function zpubToXpub(zpub) {
  var data = b58.decode(zpub)
  data = data.slice(4)
  data = Buffer.concat([Buffer.from('0488b21e','hex'), data])
  return b58.encode(data)
}

// this function takes an HDNode, and turns the pubkey of that node into a Segwit bech32 address
function nodeToP2wpkhSegwitAddress(hdNode) {
  var pubkeyBuf = hdNode.keyPair.getPublicKeyBuffer()
  var hash = bjs.crypto.hash160(pubkeyBuf)
  var scriptPubkey = bjs.script.witnessPubKeyHash.output.encode(hash)
  return bjs.address.fromOutputScript(scriptPubkey)
}

// convert zpub string into xpub string
var xpub = zpubToXpub('zpub6oFHEbYeAMTVmmmcZA5KJinUFVoGZfQhc4dBfzCMwrL1AsxopkyLv9zCKHezgHJNskU8pRUQ9AZqZjAjdZeM1ehkALJE1UNPboorWDfhPSB')

// grab the HDNode object from the xpub
var hdNode = bjs.HDNode.fromBase58(xpub)

// generate as usual, but instead of getAddress, feed into above function
var address = nodeToP2wpkhSegwitAddress(hdNode.derive(0).derive(0))
