ethereum-public-key-to-address's Issues

ETH2 public keys cannot be converted

Why does it not work with ETH2 public keys? They seem to be shorter. The error I get is:

Error: Expected public key to be an Uint8Array with length [33, 65]

I have taken the public keys from random ETH2 validators from https://beaconcha.in/validators/leaderboard
