Hello 👋
What have you tried so far?

[lyric saddle]

I've tried setting the terminal.setReaderDisplay() to a variable and then logging the output

I can see that it's a promise

But when I disconnect the card reader to simulate a failed attempt it just says pending

I'm trying to follow some basic JS promise examples online but I can't get the syntax right

[opal halo]

Can you share the code you're using?

[lyric saddle]

var request = terminal.setReaderDisplay({

        type: 'cart',
        cart: {
            line_items: info,
            tax: Math.round(tax * 100),
            total: Math.round(total * 100),
            currency: 'usd',
        }

    });

    request.then(
        function(value) {console.log('success')};
        function(error) {console.log('error')};
    );

if you just do
request.then((res) => {console.log(res)};
What are you seeing?

Uncaught syntax error when the page loads

oh wait hang on

it didn't copy properly

still the same syntax error

Am I missing something? I don't see an example provided in the Stripe docs for how to access the result of an error

I was looking through the JS docs and found an example of using a Promise so I updated my code and now there's no syntax error

var request = terminal.setReaderDisplay({

        type: 'cart',
        cart: {
            line_items: info,
            tax: Math.round(tax * 100),
            total: Math.round(total * 100),
            currency: 'usd',
        }

    }).then(function(result) {
        console.log(result);
        if(result.success) {
            console.log('success');
        } else if(result.error) {
            console.log('error');
        }
    });

But I don't get anything in the then function when the request fails

only when it succeeds

oh interesting.. This would actually need a little more time to debug/reproduce.
Do you mind writing in to our support team [e-mail] and mention that you spoke with hanzo on discord.
I'll grab the ticket and respond as soon as I can.
