# Remove deprecated errorCode and errorMessage fields from SubscriptionBillingAttempt

Starting with API version 2026-04, the `errorCode` and `errorMessage` fields on `SubscriptionBillingAttempt` are now hidden. These fields were deprecated in version 2025-01 with the introduction of `processingError`. Developers should now use `processingError.code` and `processingError.message` instead. If you haven't updated your code to use these new fields, please do so to ensure compatibility with the latest API version.
