Market.main and Network.main are undefined

[CherryDT]

The docs say to use this code:

import { TxBuilderV2, Network, Market } from '@aave/protocol-js'

const httpProvider = new Web3.providers.HttpProvider(
    process.env.ETHEREUM_URL ||
      "https://kovan.infura.io/v3/<project_id>"
  );
const txBuilder = new TxBuilderV2(Network.main, httpProvider);

lendingPool = txBuilder.getLendingPool(Market.main); // get all lending pool methods

...however this will later always produce empty transaction arrays and an error in the console that says "[LendingPoolValidator] You need to pass valid addresses".

It appears that Market.main and Network.main are both undefined!
