We run the Check Geometries Tool and it flags the data as Geometry Type Error. So I run the Multipart to Singlepart tool and….well that's where the problem is…
Which 'Check Geometries Tool'? What kind of data/file are you 'checking'? Shape file or Geopackage?
1. If I use the option [Create temporary Layer] it produces a Singlepart Geometry as Expected, If I save the output to a File, the resultant geometry is stated as Polygon (MultiPolygon) Its the same for Linestrings also.
If you say "save data to File": do you mean Geopackage?
Now I did find this.. https://github.com/qgis/QGIS/issues/50720 [1] which flags the same issues, but states that its down to the Shapefile Specification.
I read that issues as: there is (for QGIS or other tools), no way to write a singlepart line or polygon in a shapefile as the shapefile spec would not have a way to write that types in the shapefile. So when you'll ask a shapefile 'what kind of geoms have you in your belly' it could actually not tell, unless it goes over all geoms and check what is in it...
Do you have examples of files which are OK? What kind of tools do you use to check? What does for example 'ogrinfo' report to you about your 'files'?
