[Gmsh] Error Remeshing STL to Generate QUADs/HEXAs

I tried used the following geo file to remesh my STL file using quads/hexas:

Merge "mesh.stl";

Compound Surface(200)={1};


Recombine Surface {200};
Physical Surface("newSurfaceMesh")={200};

but I get this error even after adding 'Mesh.RemeshAlgorithm=1':
