Fail to generate solana address from xpub

[atlaschiew]

hi my code is very simple

defmodule Main do
  # Import block_keys functions if needed
  alias BlockKeys

  def run do
    # Example 1: Generate a random mnemonic
    root_key = BlockKeys.from_mnemonic("nurse grid sister metal flock choice system control about mountain sister rapid hundred render shed chicken print cover tape sister zero bronze tattoo stairs")

    IO.puts(root_key)
    # IO.inspect(keypair)

    %{mnemonic: mnemonic, root_key: root_key} = BlockKeys.generate()
    IO.puts(mnemonic)

    path = "M/501'/0'/0'"
    xpub = BlockKeys.CKD.derive(root_key, path, curve: :ed25519)
    IO.puts(xpub)
    IO.puts(root_key)

    address = BlockKeys.Solana.address(xpub, "M/0/0")
    #IO.puts(address)
  end
end

# Call the run function when executing the script
Main.run()

run and then i hit error below

please help

well, i expect it can derive new address from xpub without root_key
