MercadoPago.js - Form could not be submitted

[SeriusDavid]

Hi! im presenting this error without any code change on my checkout API

Im looking up for error code but i cant find any that describe this problem

we have running this implementation of the api like 3 years or so

Good afternoon! Do you have more error details to share?
I need to be able to simulate this scenario to give you a better support, you are using the cardform, correct?
this cardform is with secure fields (iframes), correct?

Can you share the application link so I can see the error as it happens and simulate?
Or maybe share with me the code snippet of your implementation?

Thanks

Hi, of course!

when you try to make the payment its when the error displays

it displays token handling error to in the javascript console

here's the link: https://www.mudango.com/payment_methods/mercado_pago/client_payment/rYkBrbDbm599tcKiMoDrtUjv

checking your code, I realized that you have more than one instance of the cardform, today it is not possible to have more than one instance of cardform on the same screen, one of the implementations is displaying for the user, and the other has display: none, follow print.

The problem is happening, because when making the payment, the validations are being sent from the first cardform, (which has display:none).

To resolve, it is necessary to remove one of the cardform from the screen.

We have been working like this for a year. Is this change new?

We are always working on improvements to our SDK, so there were probably some changes, yes, but we cannot guarantee the operation of an integration that does not comply with our documentation, thank you for your understanding.

Thanks for getting in touch, see you later!
