Attempts to retrieve the transaction processing results with Get Results activity with the same transaction ID for the second time and all subsequent times fail with error:
<DateTime>|INFO|Abbyy.Vantage.PublicApi.Client|PublicApiClient|PublicApiClient HTTP response received 404 Not Found in ... ms
If the transaction is successfully processed, it is automatically deleted after using Get Results activity on it. Next attempts to use Get Results activity refer to the deleted transaction ID, so response 404 Not Found is returned.
No resolution. The behavior is by design.
