Error when creating wallet - TypeError: Cannot perform %TypedArray%.prototype.set on a detached ArrayBuffer

[larry0x]

Describe the bug

Lodestar throws the following error when attempting to create a wallet using the yarn run cli account wallet create command:

TypeError: Cannot perform %TypedArray%.prototype.set on a detached ArrayBuffer

Expected behavior

A wallet should be successfully created

Steps to Reproduce

1. Install yarn

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt upgrade
sudo apt install yarn

2. Compile Lodestar

git clone https://github.com/chainsafe/lodestar.git
cd lodestar
yarn install
yarn run build

3. Attempt to create wallet

yarn run cli account wallet create --name myLodestarWallet --passphraseFile ~/eth2/myLodestarWallet.pass --rootDir ~/.lodestar

This gives the following error:

yarn run v1.22.4
$ node --trace-deprecation ./packages/lodestar-cli/bin/lodestar account wallet create --name myLodestarWallet --passphraseFile /home/larry/eth2/myLodestarWallet.pass --rootDir /home/larry/.lodestar

Update: this issue is resolved by downgrading Node.js to v12.18.3 and re-compile Lodestar.

@wemeetagain The error comes from @chainsafe/bls-keystore. We should make sure Lodestar is using it's latest version. Also, it would be nice to add a broad NodeJS version matrix in @chainsafe/bls-keystore tests to be sure.
