We have a layer in our Open Data site that just got updated. When the layer is downloaded as a shapefile, the attribute table is empty and users get an error when trying to open it: "Could not load data from the data source". The polygons seem to display fine and when the identify tool is used, the attributes are displayed (despite there being no information in the attribute table).
I have reset the index as well as unshared/re-shared the item, but the issue is persisting. This is a Living Atlas layer so we really need to get the shapefile download functional again.
Any suggestions are welcome.
