Hello @baixiaobai and welcome to the forums!

So, this message is saying that the vector it’s referring to has a feature that isn’t a Polygon or a MultiPolygon. Practically speaking, I sometimes encounter this issue when I accidentally have a feature that doesn’t have any geometry. You might also encounter this issue if your vector has a LineString or MultiLineString geometry. I would suggest that you use your GIS to check to make sure that all features have a geometry and that they are all polygons or multipolygons as a good first step.

Let us know how this goes!

Along with the suggestions from James, it could be possible that you have a 3D Polygon, or some other special polygon geometry that could be exported to a simple Polygon instead.
