I have a feature class and a related table that are related through a simple, 1:1 relationship class. The feature class has a field "RRNum", and the foreign key in the table is "RR". There are attachments enabled on the feature class, but I haven't found that that should be an issue. I have published them in a map service to ArcGIS Server, and both the layer and the table show up in the service information. They also display as being related to each other. However, when I go to the feature service and select "query related records", nothing will return in the query and I will get an error that says "Invalid relationshipID." They definitely show up within Pro, so I'm not sure what I'm doing wrong. Does anyone have any advice?
