As of API version 2023-07, you can use the new Subscription Contract
stale status to express a contract that has been marked as stale due to inactivity.
We're deprecating the SubscriptionDraftErrorCode
STALE_CONTRACT and replace it by
CONCURRENT_CONTRACT_UPDATE for a better description of the error.
We're introducing the new error code
CONTRACT_STALE_STATUS to SubscriptionBillingCycleErrorCode and SubscriptionDraftErrorCode to indicate whenever we attempt to update or bill a contract that hasn't been used for 1 year.
