Elastix runtime error

[Hesham3esa]

Hello I am trying to run this code
#%% Aignment - resampled to autofluorescence

align the two channels

align_channels_parameter = {
#moving and reference images
"moving_image" : ws.filename('resampled', postfix='autofluorescence'),
"fixed_image" : ws.filename('resampled'),

  #elastix parameter files for alignment
  "affine_parameter_file"  : align_channels_affine_file,
  "bspline_parameter_file" : None,
  
  #directory of the alig'/home/nicolas.renier/Documents/ClearMap_Ressources/Par0000affine.txt',nment result
  "result_directory" :  ws.filename('resampled_to_auto')
  }; 

elx.align(**align_channels_parameter);

and i am getting this error:
runcell('Aignment - resampled to autofluorescence', '/home/hesham/ClearMap2/ClearMap/Scripts/CellMap.py')
Traceback (most recent call last):

does anyone have an idea how to fix?
