I am using the dissolver to aggregate and dissolve area polygons grouping them by an ID.

I am getting the error below but when I test the incoming geometry it is all areas.

 

2020-09-13 14:27:09|20366.8| 54.1|FATAL |Expression: !isPoly || curve->isClosed2D()

 

Any ideas how this can be resolved?

Thanks

Just a hunch, but I guess that error message might mean that there is some geometrical/topological errors? Maybe polygons that are not closed (even though you said you checked - what did you use to test that?), or duplicate points, self-intersecting polygons etc.

Maybe you could check them with a GeometryValidator first, and repair them?

Hi @bubblebeb​ This looks like a problem with FME. Please submit a case if you can reproduce the problem in the latest release or betas.
