Arcpy 3.2.2 Polygon getpart issue

marceloctorres

I'm trying to get polygon parts  but I get an exception:

File "c:\Users\Mtorres\source\repos\FFP-ArcGISPro-Project\src\Public Inspection\Python Toolboxes\PublicInspectionArcGIS\Centerline.py", line 73, in _extract_parts_from_input_geometry
part = geometry.getPart(index)
File "c:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\arcobjects\arcobjects.py", line 1331, in getPart
return convertArcObjectToPythonObject(self._arc_object.GetPart(*gp_fixargs(args)))
RuntimeError: DescribeGeometry: Error in getting part from geometry

The script runs on ArcGIS Pro v3.2.2. Next script code fragment where I make the call:

        parts = []

        geometry = self.input_geometry

        if geometry.isMultipart :

            part_range = range(0, self.input_geometry.partCount)

        else :

            part_range = range(0, 1)

        for index in part_range :

            part = geometry.getPart(index)

            parts.append(part)

        return parts

 

I run the same code on ArcGIS Pro 3.1but the exception never happens.

 

Is there an error with last version of arcpy?

Thanks for your answer, I'm working with a FileGeodatabase. But  I realize that there was a issue with geometries at the feature class: Shape Areas were negatives. 

Then I used "Repair Geometries" Tool to fix geometries, and everything start to works fine.

I get this output from tool:
