000914: The 'polygon contiguity' concept is only appropriate for polygon feature classes.

Description

The polygon contiguity Conceptualization of Spatial Relationships parameter value defines feature neighbors as those polygons that share a boundary or corner. The input feature class does not contain polygon features, so this is not valid.

Solution

Specify a different Conceptualization of Spatial Relationships parameter value, or provide a different polygon input feature class for analysis.
