I need help resolving this error:
Map download failed, Unable to download map. The operation couldn't be completed. Failed to create replica. Failed to create replica.
I have a number of feature classes in an SDE which I am using to produce layers in a feature layer in portal. This layer is used in a Collector map for offline use. I have previously had this offline map working fine, I have been able to sync offline edits back to the database.
It does not use versioning. All feature classes have globalIDs, archiving and editor tracking enabled.
Today I enabled attachments, however, on these feature classes. I have checked the relationship class properties between attachment tables and feature classes, all have GlobalIDs as the origin primary key and REL_GlobalID as the origin foreign key.
There are no issues editing these layers in the online version of the Collector map, including adding attachments. Those edits upload immediately without issue. I get the above failure to create replica, issue, however, when trying to take the map with the same feature classes offline.
