Hi guys,
We are having an issue where if we have sent an invoice (order) to to square via the API, the terminal throws an error when we try to take a payment.
Here is some of the webhook data:

}
}
}
The device just shows the following after trying to take the payment with a card:
I can't seem to find any errors anywhere as it just seems to be on the device, it does however work fine if I don't try attach a order id to the checkout.
I have a bunch more webhooks if you need, although you should be able to see the checkout ID in that one and see the rest.
Kind regards,
Sam
