Import obj using python and rename it

Hi,
I’m tying to do a simple task that i’ve done and been done before so many time, but for some reason can’t seems to make it work this time.
I just wanna import obj model in the content browser using python, and adding a common sting in front of the name. For exemple, if obj is name obj_asset, I would like it to be name actor_obj_asset.
here’s the code i’ve made.

def import_asset_in_dir():
for file in glob.iglob(r’C:/Users/usr/OneDrive/Bureau/test/*.obj’):
unreal.log_warning(file)
unreal_asset_automation.import_skeletal_mesh(file, “/Game/groupe_01”, “actor” + file)

But it just ignore the last parameter. if I remove it entirely, I get a error saying I do not have input a asset name.

thanks a lot for the help !
