I am running on 9.6.3 and have a Repository with custom product fields, where one is of type integer (Int32). We call it "Minimum seats".
We then created a facet and tried to get facet options from that field, but got none. Shouldn't the Repository properly process int32 fields?
We had to create a custom index field of type string and use that field instead, just to get the proper facet options.
