Errors and troubleshooting

Code	Resolution
`CHECKOUT_CONFIGURATION_ERROR`	Check the publishable key and client secret; create a fresh Payment Intent if needed.
`CHECKOUT_SESSION_UNAVAILABLE`	Create a fresh Payment Intent.
`CHECKOUT_NETWORK_ERROR`, `CHECKOUT_UNAVAILABLE`, `CHECKOUT_TIMEOUT`	Offer retry when `retryable` is true.
`CHECKOUT_NO_PAYMENT_METHODS`	Configure and enable a payment method for the current environment.

For MountError, ensure the target element exists, the instance is not destroyed or already mounted, and no other Lynq Checkout is mounted on the page. For a failed webhook, check the endpoint URL, environment, enabled state, response status, and delivery log in Dashboard.
