BornAgain currently failing the ORSO validation suite

Since the last BornAgain release the ORSO validation script has started failing due to a BA API change, https://github.com/reflectivity/analysis/actions/runs/14697866408. I tried using the conversion script, but it wasn't able to successfully run:
