Only one element of type cardNumber can be created

I am trying to display my stripe component, but I am getting this error:

IntegrationError: Only one element of type cardNumber can be created.

I don't know why, since I'm only using it once in my entire app

Any ideas?

This is my index

import ReactDOM from 'react-dom';
import App from './App';

import * as serviceWorker from './serviceWorker';
import { loadStripe } from "@stripe/stripe-js";
import { Elements } from "@stripe/react-stripe-js";
import MyComponent from './components/StripeComponent';


const promise = loadStripe("xxx-xxx-xxx");
ReactDOM.render(
  <React.StrictMode>
      <Elements stripe={promise}>
        <MyComponent/>
      </Elements>
  </React.StrictMode>,
  document.getElementById('root')
);

And this is my component

import React from "react";
import {
  useElements,
} from "@stripe/react-stripe-js";

const MyComponent: React.FC= (props)=>{

  const elements = useElements();


 
    const cardNumberElement = elements?.create('cardNumber', {
      placeholder: ''
    });
    const cardExpiryElement = elements?.create('cardExpiry', {
      placeholder: ''
    });
    const cardCvvElement = elements?.create('cardCvc', {
      placeholder: ''
    });
    
    cardNumberElement?.mount('#card-number-element')
    cardExpiryElement?.mount('#card-expiry-element')
    cardCvvElement?.mount('#card-cvv-element')

 


  const handleSubmit = async (ev: any) => {
    ev.preventDefault();
    

  };
  return (
    <form id="payment-form" onSubmit={handleSubmit}>
      <div id="card-number-element"></div>
      <div id="card-expiry-element"></div>
      <div id="card-cvv-element"></div>
    </form>

  );
}

Seems it is because you create and mount the card components in the functional component body they are executed on every render of the component, i.e. as an inadvertent side-effect.

Place the creation and mounting logic in an useEffect hook with an empty dependency array so that it is invoked only once when the component mounts.

import React, { useEffect } from "react";
import { useElements } from "@stripe/react-stripe-js";

const MyComponent: React.FC = (props) => {
  const elements = useElements();

  // Effect hook to run once on component mount
  useEffect(() => {
    const cardNumberElement = elements?.create("cardNumber", {
      placeholder: ""
    });
    const cardExpiryElement = elements?.create("cardExpiry", {
      placeholder: ""
    });
    const cardCvvElement = elements?.create("cardCvc", {
      placeholder: ""
    });

    cardNumberElement?.mount("#card-number-element");
    cardExpiryElement?.mount("#card-expiry-element");
    cardCvvElement?.mount("#card-cvv-element");
  }, []); // <-- empty dependency array

  const handleSubmit = async (ev: any) => {
    ev.preventDefault();
  };

  return (
    <form id="payment-form" onSubmit={handleSubmit}>
      <div id="card-number-element"></div>
      <div id="card-expiry-element"></div>
      <div id="card-cvv-element"></div>
    </form>
  );
};

I had the same problem, in my case, I had a reference to CardNumberElement in another section of my code. After removing it, everything worked fine.

useEffect(() => {
  if (elements) {
    const cardNumberElement =
      elements.getElement("cardNumber") || // check if we already created element
      elements.create("cardNumber", defaultInputStyles); // create if dont

    cardNumberElement.mount("#numberInput");
  }
}, [elements]);
