Pagseguro - Problem when consulting Brand

Question

Hello, I am trying to use the transparent checkout of pagseguro. I have already integrated the session generation, but when consulting the flag of the card, the function success is never called, only error and complete. However, the answer never shows which error, only shows that it exists, with response.error = true.

I’m using the example documentation code, so I can’t understand what the error is in this case. Follow the function code below:

PagSeguroDirectPayment.getBrand({
  cardBin: 4111111,
  success: function (data) {
    alert(data);
  },
  error: function (response) {
    console.log(response);
  },
  complete: function (response) {
    console.log(response);
  },
});

I am developing Back-End in Django, and using Jquery 3.5.1. Is there an error in my code? Thank you.
