Stripe API "No valid payment method types for this Payment Intent."

As you can imagine I´m currently setting up the payment API with using Stripe. Problem is, I´ve never done such thing before and am following the docs pretty much 1 by 1.

So I require stripe using (100% the right!) key.

const stripe = require("stripe")(
  "keyhere"
);

create the intent in a method...

const paymentIntent = stripe.paymentIntents.create({
  amount: process.env.AUDIT_PRICE,
  currency: "eur",
  automatic_payment_methods: { enabled: true },
});

call that method on a certain express route:

exports.createNewCashOrder = async (req, res) => {
  const intent = await paymentIntent();
  res.json({ client_secret: intent.client_secret });
};

The rest is irrelevant for now, since my backend server doesn´t even start on localhost. Actually it´s live for like 0.001 seconds and than crashes with this error:

StripeInvalidRequestError: No valid payment method types for this Payment Intent. Please ensure that you have activated payment methods compatible with your chosen currency in your dashboard

It also sends back a large error object, where at the end it says that pretty much everything (also the payment methods) are undefined.

Now on my dashboard, I did activate card payment, but it obviously somehow does not recognize it...

Any ideas what I´ve done wrong? Glad for any help, thanks!
