Bitcoinjs-lib: bip32 from bip39: Error: Expected Buffer, got Promise

[tiero]

My dependencies:

    "bip32": "^1.0.3",
    "bip39": "^3.0.0",
    "bitcoinjs-lib": "^5.0.0"

If I do

const mnemonic = 'praise you muffin lion enable neck grocery crumble super myself license ghost'

const seed = bip39.mnemonicToSeed(mnemonic)
const root = bip32.fromSeed(seed)

const node = root.derivePath("m/0'/0/0")

It stops with

Error: Expected Buffer, got Promise

It seems that bip32.fromSeed(seed) now it returns a promise to be solved?

Use bip39 v2 or switch to mnemonicToSeedSync.

v3 changed the API to use async Promises which are faster

Can also resolve promises as follows 👍
`const mnemonic = 'praise you muffin lion enable neck grocery crumble super myself license ghost'

const seed = bip39.mnemonicToSeed(mnemonic)
seed.then( s => {
const root = bip32.fromSeed(s)
const node = root.derivePath("m/0'/0/0")`
})
