There are three possible geometry types for a layer: points, lines, and polygons. The two selected layers must have the same geometry type.
Solution
To resolve the error, do one of the following:
- Select input layers that have the same geometry as each other.
- Use Find Centroids to create point features from lines or polygons.
- Use Create Buffer to create polygons from points or lines.
