facefusion.py: error: unrecognized arguments

[Supergatti]

My code was like:
def process_task(task_id, selected_face_image, target_image_path, output_path):
try:
os.system(
f'python "{facefusion_script}" job-add-step {task_id} --source-paths "{selected_face_image}" --output-path "{output_path}" --target-path "{target_image_path}" --face-selector-mode reference --processors face_swapper face_enhancer --face-swapper-model inswapper_128_fp16 --face-enhancer-model gfpgan_1.4 --face-swapper-pixel-boost 512x512 '
)
return True
except Exception as e:
print(f"Error adding task step: {e}")
return False
but I get:
