Jet Starter Error - Page Not Found

Question

I created a new route from the action-starter-kit project, and it selects some data asynchronously and then displays them, but after a second the page reloads with the message "Page not found", sorry, but the page you are trying to view does not exist. "

In the console, I see - “Warning: text content did not match” Server: “Remains” Client: “Page not found”

async function action() {

let bittrex = new ccxt.bittrex ({
    'apiKey': '',
    'secret': ''
})

try {

    // fetch account balance from the exchange
    let bittrexBalance = await bittrex.fetchBalance ()
    /**** commenting above and uncommenting this block stops it from happening.... 
    let bittrexBalance = {};
    bittrexBalance.info= [];
    let currency = {};
    currency.Currency = "BTC";
    currency.Value=999;
    // output the result
    bittrexBalance.info.push(currency);*/
    console.log ('balance', bittrexBalance)

    let balances = [];
    balances.push(bittrexBalance)
    return {
        title: "Balances",
        component: (
            <Layout>
                <Balances balances={balances} />
            </Layout>
        ),
    };


} catch (e) {
    console.log('SOME sort of error', e);
}

Does anyone know what this could be?

Edit to add, now I understand that if I turn off Javascript everything will work just fine ...

It seems to work through the universal router twice. For the first time
