API Mercadopago: How to generate a new Payment Token, after a "payment" rejected

Testing in Sandbox environment, I have an app that generates a "payment token", which I then send to the server to generate the "payment".
The scenario is during the test of error messages:

I try insufficient funds, I add FUND in front of the name

I receive the corresponding error, until here everything is correct.

change to test expiration, add EXPI before the name.

gives me error 400, bad_request, complete error message: "could not update the Card with the following id: b67f82b44375001c136081b3b392f1f7 because it has been used or expired"

I understand that the token can only be used once and apparently the API wants to update it, when in fact it should generate a new one.

Any ideas that I should be doing wrong?

Mercadopago's documentation is incomplete and not very clear.

But by reviewing the Mercadopago class of the JavaScript SDK, you can see a prototype called clearSession (), which effectively does what is expected.

// limpiar sesion, luego de "payment" rechazado
Mercadopago.clearSession();

// validar que el usuario no utilice los mismos datos rechazados.
validarForm();

// generar nuevo token luego de pago rechazado
Mercadopago.createToken(form, callback);

// procesar nuevamente el pago
crearPago();
