240036: Output public transit data model feature classes exist in the geodatabase but are not within the target feature dataset. A feature class name can only exist once within a geodatabase, including within all feature datasets.

Description

The public transit data model includes feature classes and tables with specific names. Feature classes or tables with one or more of these names exist in the geodatabase and are not located in the target feature dataset specified as a tool input. Duplicate feature class and table names are not allowed within a geodatabase, and these feature classes and tables are causing a naming conflict with the tool's output.

Solution

Delete the existing data or choose a different geodatabase for the tool output.
