Hello! Not sure what you mean by it not being async? Can you show me the code you're using to handle that event?
crystal sapphire
Okay, and how exactly isn't this working as expected?
finite fern
The call to this.updateCart seemingly isn't awaited... that's what I meant by maybe the callback function is not allowed to be an async function
So the console prints the same thing before and after... whereas with paymentRequest, that call to updateCart is awaited, and the tax_total on the cart changes between the two console logs
This was the paymentRequest version
crystal sapphire
You're specifying it as an async function, so it should be awaiting that. I don't see how we could be preventing that from happening.
finite fern
Okay, so it does support an async function there the same as paymentRequest
crystal sapphire
It should, yeah.
finite fern
Is there something wong with event.resolve vs event.updateWith?
Just looking for differences... another dev left me with this overnight so I am trying to figure it out
crystal sapphire
You need to use resolve with the Express Checkout Element. See here: https://docs.stripe.com/js/elements_object/express_checkout_element_shippingaddresschange_event
finite fern
Okay, so that seems okay
I guess the crux of the issue is that the Google Pay (in this case) dialog doesn't update to reflect updated tax info
So the user doesn't see that they have to pay tax after they enter their shipping address
crystal sapphire
You're trying to add the tax as a line item?
finite fern
Yeah it's in lineItems in the first screenshot. And previously it was in displayItems (for payment request)
crystal sapphire
Seems like it should be working. Are you certain the line items being set there are what you expect?
Or, wait, are you saying your updateCart function is supposed to calculate tax, but it's not, so your second console.log shows the same tax value as the first one?
finite fern
No I misspoke on that -- the console logs the correct tax value, but it's not reflected on the Google Pay dialog
The first two logs show it going from 0 to 15.26.
And that value is sent in event.resolve
crystal sapphire
Can you log the actual line items you're passing in and make sure those are correct?
Are you seeing the same incorrect behavior with Apple Pay as well?
finite fern
Yeah the only difference is the conversion from dollars to cents I guess... let me revert back to the expressCheckout version and log, and also try Apple Pay... will be a few
Okay I got this console error: Unhandled Promise Rejection: IntegrationError: The amount 8597 is less than the total amount of the line items provided.
So it actually seems like it's updating the lineItems with the new tax amount now. But that means the sum of all the lineItems together is greater than the original total that was sent. Can the total also be updated in the lineItems?
crystal sapphire
No, I believe you would need to update the amount on the elements instance separately: https://docs.stripe.com/js/elements_object/update#elements_update-options-amount
finite fern
Aha... okay that is different from how paymentRequest worked I guess. I'll try that.
