Issue or question about MOOSE

Hi everyone, I've been having a lot of trouble with MOOSE recently. I'm a beginner and I am trying to get MOOSE to read a file with a mesh but I keep getting an error saying that the nodes can't be found. However, I know that the unv file has nodes and a mesh so I don't understand why this is happening. I don't think it's an issue from my input file because my colleague can't seem to find anything wrong with it. Has this ever happened to anyone? If so how have you fixed the issue? Any help would be greatly appreciated, thank you.

Hello

The .unv file must not be read properly. Or it is nor formatted as expected.
How did you generate it?
Can Paraview read it?

[Mesh]
    [mesh]
      type = FileMeshGenerator
      file = 'HYLIFE_II_2D_medium.unv'
    []
     [merge]
       type = RenameBlockGenerator
       input = mesh
       old_block = 'Solid_1 Solid_2'
       new_block = '0 0'
      []
      construct_side_list_from_node_list=true        

This is how I generated the mesh in moose, I created the mesh from salome though. I'm having a bit of trouble reading it in paraview because there are no local readers for a unv format.

[GiudGiud]

.unv is for
I-deas Universal format

is that what salome is creating?

what is the list of options in salome?
all the ones we can read are there:
