swaps.fetchPools(); error

[hitdavid]

I try a demo code:

const balancer = new BalancerSDK({
    network: 1, // Mainnet
    rpcUrl: "https://my-eth-rpc" // rpc endpoint
  })

  const { swaps } = balancer // Swaps module is abstracting SOR
  const pools = await swaps.fetchPools();

throws exception:
