An old thread, but I'm facing a similar issue. This is the error message from tomcat-stdOut.log

[Appian Work Item - 708446 - WorkID 198 - execution01 - process 269299497 - model 3708 : UnattendedJavaActivityRequest] ERROR com.appiancorp.process.engine.UnattendedJavaActivityRequest - An error occurred while executing activity: id=268462135, classname=com.appiancorp.process.runtime.activities.MultiWriteToDataStoreSmartService com.appiancorp.common.xml.JaxbConversionException: XML handling failure trying to convert value EntityData [entity=DataStoreEntityRef[id=2908b8f1-3e8f-446f-b573-4083e8e197b4@87164, uuid=null], data=[TypedValue[it=12446,v={1500,1597,,,,,,,,,84,2025-09-17 06:28:53.91,84,2025-09-17 07:13:16.86,1,1,Approved 👍,1,84,3,}]]] to Appian type EntityData (id=1134)

Notice the thumbs up emoji towards the end.

The issue only occurs when using the "Write to multiple Data Store Entities". When passing the same data to the single "Write to Data Store Entity", the data is successfully saved to the DB.

OK. Then the issue is that your database table is not configured correctly.

Thanks for your response Stefan, the error is resolved now, It was the "emoji" which was inserted. End user has removed that and it got saved into DB now

Can you share the exact configuration of that process node?

No Stefan, I did not find any details in log which is helpful. All i can see is "Could not find ids"

Do you see any additional details in the tomcat stdout log file?
