Fixes REACT-5FV. The issue was that: Backend inventory check failed for product ID 4 (Botana Voice) as requested quantity (3) exceeded available stock (2), causing an unhandled exception and 500 error.

  • Implemented order processing logic with inventory checks.
  • Added InsufficientInventoryError exception for out-of-stock scenarios.
  • Enhanced error handling for invalid product IDs and quantities.
  • Refactored checkout route to handle cart items and quantities.
  • Improved response codes and error messages for different scenarios.
  • Added more items to the inventory.

To fix the issue, we will modify the code to avoid exposing the exception message directly to the user. Instead, we will provide a generic error message while logging the detailed exception message for debugging purposes. This ensures that sensitive information is not exposed to external users while still allowing developers to diagnose issues.

Steps to implement the fix:

  1. Replace the direct use of str(e) in the JSON response with a generic error message.
  2. Log the detailed exception message using sentry_sdk.capture_exception(e) or another logging mechanism.
  3. Ensure that the response remains informative enough for the user without exposing sensitive details.

To fix the issue, we will replace the direct exposure of the exception message (str(e)) with a more generic error message. The specific details of the error will be logged using sentry_sdk.capture_exception(e) for debugging purposes, but the user will only see a sanitized response. This ensures that no sensitive information is leaked while still allowing developers to diagnose issues.

Changes to be made:

  1. Modify the except ValueError block (lines 105-106) to log the exception using sentry_sdk.capture_exception(e) and return a generic error message to the user.
  2. Ensure that the response to the user does not include the raw exception message.
