Unable to catch some python node warnings with try/except

HI there!
Curious case here over the last week. Using Dynamo 2.3.0 with Revit 2020.2.3: a python node generates warnings that I can’t catch with a try: except: code or trace, and that do not interrupt execution of the script. Never seen anything like that happening. Common in the warnings I have isolated so far is that they have to do with geometry creation, typically starting with: <Warning: One or more geometries have failed to convert due to this error>. Anyone familiar with this? I have not found any reference to this behaviour in a search. Bug or feature?

Examples, also unable to determine if these are just the first that pop up or a complete list:
Warning: One or more geometries have failed to convert due to this error: trim_with_edge_loops requires all curves to touch surface
Warning: One or more geometries have failed to convert due to this error: PolyCurves may be branching
Warning: One or more geometries have failed to convert due to this error: The call is ambiguous between the following methods or properties: ‘Revit.GeometryConversion.GeometryObjectConverter.Transform(System.Collections.Generic.IEnumerable<Autodesk.DesignScript.Geometry.Geometry>, Autodesk.DesignScript.Geometry.CoordinateSystem)’ and ‘Revit.GeometryConversion.GeometryObjectConverter.Transform(Autodesk.DesignScript.Geometry.Geometry, Autodesk.DesignScript.Geometry.CoordinateSystem)’
