I am having a new issue with an enterprise hosted layer that has worked for years with no issue. When downloading an offline area of a map hosted on our server, attempts to sync the offline map occasionally push out the error code 1005 for updating a polygon layer. I have looked up the error code and it says true curve updates are not allowed. When editing the polygon, the only edits are to the attribute table, not to the geometry at all. On top of that, each polygon in the separate downloaded map area does not have any curves in its geometry - and it only happens with some areas that are downloaded, other areas sync just fine.
I am otherwise able to edit the attribute table for the polygons in Field Maps if it is being updated from the map and not from a downloaded offline map area. I can also edit the table in Map Viewer through the portal as well as from ArcPro projects containing the hosted layer, it is only syncing the offline map areas in Field Maps that seems to have this issue. I have attempted a host of solutions, including repairing the geometry, exporting to a new feature class and rehosting the layer, and addressing any potential of data corruption - all to no avail. Wondering if anyone might have any insight to this issue.
