I am getting the below error when updating data of a synced record using a process that has Write to Data Store Entity nodes and Write to Multiple Data Store Entities nodes.
[Appian Work Item - 773428 - execution02 : UnattendedJavaActivityRequest] ERROR com.appiancorp.record.service.RecordReplicaUpdateService - Loading updates to synced record type(s) in ADS failed, invalidated record type(s): [(da0a35ad-c98f-40e7-975c-47ff016a2084,WMS Request)] com.appiancorp.suiteapi.common.exceptions.AppianException: Unable to sync due to a system failure.

This error is not covered in the docs so unable to find guidance on how to resolve it - docs.appian.com/suite/help/21.4/Records_Monitoring_Details.html#other-sync-errors
Has anyone run into this error? What does "Cannot update the same entity multiple times in the same transaction" mean? I should be able to write or update the Request record how many ever times I want in the process.
Here is a short desc of the data model and the process that updates the synced record:
Unable to sync due to a system failure. Issue identifier: [1e56f60d-f25a-43fe-bb1b-c2e9861abd60]

For what it's worth (also mentioned under this Discussion, which gave me a hint to the potential underlying issue):
I recently ran into this exact error message and scenario (writes to DSE consistently caused Record Type's data sync to fail, even though the data changes do get persisted, and manually running a data sync has no problems). In my case, the underlying database table's PK was configured as INT UNSIGNED. When I updated it to be simply INT, the data sync errors on DSE writes went away.
I have no idea why the use of UNSIGNED might cause this data sync error, or why Appian might complain about updating "the same entity multiple times in the same transaction", when that's not what was going on.

I am facing similar kind of an issue where the record is sync is failing randomly. We are using record sync smart service in a process model. NOTE: when performing manual sync or scheduled sync then it never fails. It is only failing when using smart service and that too randomly. Few times it is success but few times it fails. There is no defined pattern at times it fails around 300s and at ties it fails within 26s.
We tried checking the stdout logs but there is no clear error message. we have identified few different kind of errors in the logs as below:
Can you please provide any insight/help of what these errors are?
I would suggest opening a ticket with Appian support.
Just wanted to add one more info, we have done SAP integration through which we are sourcing data in the record.
