Mesh.GetOutlines minimizing probability of null

Hi @dale would you mind recommending steps to minimize getting null out of Mesh.GetOutlines(plane) method? Can I do something with mesh earlier to ensure that I will get an outline?

I’m facing weird behavior as I have mesh which gives an outline in its original form but if I’ll scale it 10 times I’m getting null here and to be honest I don’t have a clue what can cause such situation. Inspected this mesh in IDE and mesh is valid. I tried QuadsToTris, ComputeFaceNormals, UnifyNormals, Compact.

Here is GH file showing the problem - meshes are internalized:
