I got errors when trying to compile the query script

witnet/EthPrice.js content:

import * as Witnet from "witnet-requests"

const binance = new Witnet.Source("https://api.binance.US/api/v3/trades?symbol=ETHUSD")
  .parseJSONMap()
  .getFloat("price")
  .multiply(10 ** 6)
  .round()

const coinbase = new Witnet.Source("https://api.coinbase.com/v2/exchange-rates?currency=ETH")
  .parseJSONMap()
  .getMap("data")
  .getMap("rates")
  .getFloat("USD")
  .multiply(10 ** 6)
  .round()

const kraken = new Witnet.Source("https://api.kraken.com/0/public/Ticker?pair=ETHUSD")
  .parseJSONMap()
  .getMap("result")
  .getMap("XETHZUSD")
  .getArray("a")
  .getFloat(0)
  .multiply(10 ** 6)
  .round()

const aggregator = Witnet.Aggregator.deviationAndMean(1.5)
const tally = Witnet.Tally.deviationAndMean(2.5)

const query = new Witnet.Query()
  .addSource(binance)
  .addSource(coinbase)
  .addSource(kraken)
  .setAggregator(aggregator) // Set the aggregator function
  .setTally(tally) // Set the tally function
  .setQuorum(10, 51) // Set witness count and minimum consensus percentage
  .setFees(5 * 10 ** 9, 10 ** 9) // Witnessing nodes will be rewarded 5 $WIT each
  .setCollateral(50 * 10 ** 9) // Require each witness node to stake 50 $WIT

// Do not forget to export the query object
export { query as default }

Here is output

/Users/user/.nvm/versions/node/v18.20.0/bin/yarn run witnet:compile
yarn run v1.22.22
$ rad2sol --verbose --write-contracts
