Does not return any rates

[madmacc]

oxr.timestamp undefined
oxr.base USD
oxr.rates {}

const oxr = require('open-exchange-rates');
oxr.set({ app_id: OXR_APP_ID })

await oxr.latest();
  // You can now use `oxr.rates`, `oxr.base` and `oxr.timestamp`
  console.log('oxr.rates', oxr.rates);
  console.log('oxr.base', oxr.base);
  console.log('oxr.timestamp', oxr.timestamp);

Using version 0.3.0
My app id works fine using:
https://openexchangerates.org/api/latest.json?app_id=

UPDATE:
It appears it doesn't work with "await".
The following works but I am not sure how to use it like that for my use case as I need to wait for the results and then do something else.

 oxr.latest(function() {
    // You can now use `oxr.rates`, `oxr.base` and `oxr.timestamp`
    console.log('oxr', oxr);
    console.log('oxr.rates', oxr.rates);
    console.log('oxr.base', oxr.base);
    console.log('oxr.timestamp', oxr.timestamp);
  });
