Converting HDF to Sarif using sarif-multitool@4.5.4 results in System.IndexOutOfRangeException

[RLI-Rdeaton]

Consider the following HDF file.

example.hdf.json.zip

Performing the following command on this data:

DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 sarif-multitool convert -t Hdf -o openscap-report.sarif openscap-report.hdf.json

Results in the following error:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

The HDF in question was generated from a valid openscap XCCDF , using a profile available at https://github.com/chainguard-dev/stigs .

I'm pretty flummoxed as to what the issue could be, as I'm able to generate SARIF files from this otherwise.
