I have 2 forms set up. 1 for a Polygon feature layer with a related Point feature layer. That survey123 form publishes with no issues. The other form is Polyline feature layer with a related Point feature layer. This service gives the error.
Both forms point to separate feature services which have the Polygon/Point and PolylinePoint respectively. I can see no difference as to how the services or forms are set up, but cannot get the Polyline service to publish.
The workflow is for field person to walk or draw a perimeter (polygon) or line(like a creek or fence) for the line feature, but to have photos that are related to the feature be at the spot of the photo, vs, click anywhere on a line or polygon. As I said, the Polygon/Point publishes, but the Polyline/Point fails on the error above.
Any help or ideas would be greatly appreciated.
I would be helpful if you could attach or provide directly via e-mail (jtedrick AT Esri.com) the form and feature service information that is experiencing the issue. From the error message, it sounds like the form is possibly 'pointed' at the wrong layer in the feature service.
