We added a custom field to the RetailTransactionTable and created an extension table called RetailTransactionTable_DLX, as indicated in the CDX extensibility documentation.
When creating an offline transaction and then switching back online, we encounter an error during the purge of records from the offline table.
The error message is: "Offline data sync failed. Offline may not be available or have the latest data. Please contact your administrator for further assistance." Error codes: "ASYNC_CLIENT_FAIL_PURGE_OFFLINE_TRANSACTION_DATA" Error message: "The offline transaction data could not be purged from the offline database."
Store commerce version is the 9.54.25182.8.
