InventorLoader Ipt to Step is not working.

Hi, I just found this workbench to convert a model to step. It looks like it is not working for me. I am not sure if this is a problem with my ipt model or a problem with the InventorLoader. I am going to share the output of Freecad, here.

I selected to import the step, but it looks like it is importing all the options presented in the popup window.

20:39:25  Importing: /home/lheck/Downloads/Caja_Metalica_Octagonal.ipt
20:40:06  pyException: Traceback (most recent call last):

I am also attaching the file here. Caja_Metalica_Octagonal.zip

According to the log the model has been successfully converted, but failed writing the STEP file /home/lheck/Downloads/Caja_Metalica_Octagonal_ipt/0016.step.

This is not a problem of this library.
