custom path cast volume tomwer widget

When trying to use a keyword to create a custom output path where to cast the volume as 16bit tiff, like so:

/data/visitor/ihma724/id19/20250909/PROCESSED_DATA/007_carbon_twill_1_test/007_carbon_twill_1_test_0001/volume_16bit/{scan_basename} (I tried all keywords suggested in https://tomwer.readthedocs.io/en/stable/canvas/widgets/reconstruction/castvolumewidget.html)

I get the following error:

2025-09-11 12:05:17 [PROCESS_STARTED] start cast volume hdf5:scan:/home/esrf/rofische/data_ihma724/PROCESSED_DATA/007_carbon_twill_1_test/007_carbon_twill_1_test_0001/007_carbon_twill_1_test_0001_1_1_0009.nx?path=entry0009 with parameters {'output_data_type': 'uint16', 'output_file_format': 'tiff', 'output_dir': '/data/visitor/ihma724/id19/20250909/PROCESSED_DATA/007_carbon_twill_1_test/007_carbon_twill_1_test_0001/volume_16bit/{scan_basename}', 'overwrite': True, 'rescale_min_percentile': None, 'rescale_max_percentile': None, 'data_min': 0.1191, 'data_max': 3.3006, 'compression_ratios': None, 'remove_input_volume': True, 'cluster_config': None}
**2025-09-11 12:05:17 [ERROR] 'scan_basename'**

How much would it take to add 3D tiffs as an option instead of piles of 2D tiffs of different scans in the same folder? I find the default structure with deeply nested folders not very useful.

Otherwise, the workflow for scan series works very nicely.
