Cannot update credit card using session

I'm trying to update a credit-card using the StripeCheckout, I saw that another user has asked a similar thing here.

The problem's that I'm not able to replicate the session object without passing any amount, I did:

const domainURL = process.env.APP_DOMAIN;

let opts = {
    payment_method_types: ["card"],
    mode: 'setup',
    success_url: `${domainURL}/pay/success?session_id={CHECKOUT_SESSION_ID}`,
    cancel_url: `${domainURL}/pay/cancel`
};

// Make session
let session = await stripe.checkout.sessions.create(opts);

let url = `${domainURL}/pay/checkout-session?sessionId=${session.id}`;
return url;

the code above generate the url for Stripe session, and the following window is opened:

so this seems to works apparently, but when I save the card clicking on "Salva carta" I get:

UnhandledPromiseRejectionWarning: Error: Stripe: Argument "id" must be a string, but got: null (on API request to GET /customers/{id})

I also tried:

 let opts = {
        payment_method_types: ["card"],
        mode: 'setup',
        setup_intent_data: {
            metadata: {
              'customer_id': 'customer id',
            }
        },
        success_url: `${domainURL}/pay/success?session_id={CHECKOUT_SESSION_ID}`,
        cancel_url: `${domainURL}/pay/cancel`
    };

as described here
