IB has changed the timezone format in TWS 10.17+ and now it requires us to provide timezone at the end of the dates.
See info here: https://forum.amibroker.com/t/please-look-at-timeinforce-part-of-place-order-code/31980/3

So instead:

let details = await api.getHistoricalData({
    contract: Contract.stock('AAPL'),
    endDateTime: '20200308 12:00:00,
    duration: '1 D',
    barSizeSetting: '1 min',
    whatToShow: 'TRADES',
    useRth: 1,
    formatDate: 1
});

Valid date format is now:

let details = await api.getHistoricalData({
    contract: Contract.stock('AAPL'),
    endDateTime: '20200308 12:00:00 US/Eastern', // or for UTC: 20200308-12:00:00
    duration: '1 D',
    barSizeSetting: '1 min',
    whatToShow: 'TRADES',
    useRth: 1,
    formatDate: 1
});
