Root Cause

• Incorrect payment lifecycle transitions: The payment was attempted in a state that does not allow processing (e.g., already completed, canceled, or expired).
• Gateway synchronization issues: The payment gateway system is not aligned on the current state of the payment.
• System timing issues: The payment attempt occurred after a state change that rendered the payment invalid.

Troubleshooting and Solutions

• Inform the customer that their payment could not be processed due to an unexpected issue.
• Ask the customer to retry the payment by initiating a new transaction.
• Ask the customer to contact support if the issue persists after retrying.
• Check your system logs and payment gateway status to confirm the current payment intent status.
• If the problem persists, contact Chargebee Support for investigation and resolution.
