I have the following in a serverside function:

`async function processPayment(paymentRequest: any, environment: ‘sandbox’ | ‘production’) {  
const client = new Client({  
environment: environment === ‘sandbox’ ? Environment.Sandbox : Environment.Production,  
accessToken:  
environment === ‘sandbox’  
? process.env.VITE\_SQUARE\_ACCESS\_TOKEN\_DEV  
: process.env.VITE\_SQUARE\_ACCESS\_TOKEN\_PROD  
});

```
try {
	const { nonce, amount, currency, userId, paymentType, eventId, eventDescription, userEmail } =
		paymentRequest;

	console.log('Processing payment:', paymentRequest);

	if (!nonce) {
		throw new Error('Payment nonce is missing');
	}

	// Create a payment request using the Square API
	const paymentsApi = client.paymentsApi;
	const response = await paymentsApi.createPayment({
		sourceId: nonce,
		idempotencyKey: uuidv4(), // Generate a unique idempotency key
		amountMoney: {
			amount: amount, // Example: 100 for $1.00
			currency: currency || 'USD'
		}
	});

	if (
		!response.result ||
		!response.result.payment ||
		response.result.payment.status !== 'COMPLETED'
	) {
		throw new Error(`Payment failed: ${response.result.payment?.status || 'Unknown error'}`);
	}`

```

This works with no issues when running it in development mode locally. However, when running in production, i get this error

```auto
"code": "INVALID_CARD_DATA","detail": "Card nonce not found in this application environment. Please ensure an application ID belonging to the same environment is used when generating the nonce.","category": "INV… [message truncated due to size]

```

Im not sure what to do, my client and server are configured correctly. Is there a mistake I am making here?

The error message suggests that the card nonce was generated in a different environment than the one you’re trying to use it in. If you generate a nonce in a sandbox environment, you can’t use it in a production environment, and vice versa.

Ensure that both your client-side and server-side environments match. If you’re testing in a sandbox environment, make sure your client-side code is also generating nonces in the sandbox environment. Similarly, if you’re in a production environment, ensure your client-side code is generating nonces in the production environment.

Also, make sure that the access token you’re using on the server-side matches the environment you’re working in. If you’re in a sandbox environment, use your sandbox access token, and if you’re in a production environment, use your production access token.
