The error message, “ERROR: code:500, Required property name is missing., Internal server error” is returned while adding the InfrastructureProjects layer from the Capital Project Planning solution in ArcGIS Pro.

Workaround

1. Download the hosted feature layer as a file geodatabase from Portal for ArcGIS 11.2 and remove the attachments and the relationship class from the data.
2. Reconfigure the relationship class and enable attachments on the feature class and publish it as a new hosted feature layer. It can now be successfully added in ArcGIS Pro. However, views must be created and the layer must be reconfigured in the web maps and web apps associated with the Capital Project Planning solution.
