Error from file mesh transform

[makeclean]

Hi

I have the following mesh block

[Mesh]
  [div_mesh]
    type = FileMesh
    file = 'divertor-monoblock-htc.e'
    use_displaced_mesh = false
  []
  [rotate]
    type = TransformGenerator
    input = div_mesh
    transform = SCALE
    vector_value = '0.01 0.01 0.01'
  []
[]

However, moose complains that

*** ERROR ***
Task add_mesh_generator is not registered to build MooseMesh derived objects

But as far as I can tell its no different to this from example test/tests/mesh_modifiers/transform/rotate_and_scale.i

[Mesh]
  [file]
    type = FileMeshGenerator
    file = cylinder.e
  []

  [rotate]
    type = TransformGenerator
    input = file
    transform = ROTATE
    vector_value = '0 90 0'
  []

  [scale]
    type = TransformGenerator
    input = rotate
    transform = SCALE
    vector_value = '1e2 1e2 1e2'
  []
[]

Any ideas?

Dear makeclean,

I just had the same problem, you need to use FileMeshGenerator instead of FileMesh in the first block.
