Offline data sync issue

Dear Friends,

I am using ArcGIS Enterprise 11.5 , ArcGIS Pro 3.5.5, Database - SQL Server, Utility Network data - UtilityNetwork version 6.

I am working ArcGIS field maps to for field survey and update feature information using ArcGIS field maps app. I am able to create and submit features using online. But when it comes to offline, I was failed to sync my updates. I am getting the below error in arcgis server log when I click sync offline edits in ArcGIS field maps app in my iphone/ipad.

I am getting this issue with both UN data and GN data.

I am workflow is follows.

Create ArcGIS Pro Project using Electric UN data (Data referencing to SQL server database). ->Banch version enabled-> Publish as web layer (capabilities like add/update/delete/sync enabled). -> Created a Web map using the Feature service URL -> Created a form for one of the layer (say ElectricDevice) with basic one or two fields->Accessing the web map in ArcGIS field maps app -> Feature create and submit working in online -> Created a offline area -> Switched off the Internet in device(ipad) -> created a feature with attrbutes updates and submitted -> Switch back to online -> Open the same web map -> looked for Sync option, clicked on sync-> I dont see any errors in iPad, but no features are moved to online version. and I am seeing above error in server log.

Please help on where I am missing , and I need to look for.

Thanks in advance.

Thanks,

Ashok

Have you looked at the troubleshooting logs in Field Maps App? That might give a better idea of what is going on.

I say that as the two errors in the log you posted seem to appear at least once or twice a day since AGS 10.6.1 (still in 10.8.1 and 10.9.1) and tech support finally gave up on trying to figure out why. So, I kind of doubt it is related to the offline issue.

Never seems to cause any issues that we've noticed. But, I have not tried offline with Portal, nor branch verioning.
