TypeError when using lung_nodule_ct_detection

[fordanic]

Describe the bug
I have downloaded the lung_nodule_ct_detection bundle (0.5.9) and I try to follow the steps of https://docs.monai.io/projects/monai-deploy-app-sdk/en/latest/notebooks/tutorials/06_monai_bundle_app.html# to create a MAP using the downloaded bundle. Unfortunately, I fail already when trying to run the app locally, i.e., using something like:

app = LungNoduleDetectionApp()

app.run(
    input=str(input_dir),
    output=str(output_dir),
    model=str(model_dir),
)

This fails with the following error:
