ExportToPDF fails with "ValueError: Type names and field names must be valid identifiers: 'st_area()/'st_length()'" for SDE polygons and line feature classes.

解决办法

• Use a file geodatabase feature class instead.
• Create center points from the SDE line/polygon feature class using a tool like Feature to Point and basemap series on the SDE point feature class instead.
