Summary

I wanted to try out this tool and just ran it. It didn't produce any usable output and just threw a cryptic error.

Background

$ docker run -it --rm \
    -v "$(pwd):/repository" \
    -v "$(pwd)/out:/out" \
    spdx/spdx-sbom-generator -p /repository/ -o /out/

Expected behavior

I don't know what to expect, but it's not this.

Repository

Which repository causes this error?

I’m seeing essentially the same behavior though in a python environment:

It seems like this is related to https://github.com/opensbom-generator/spdx-sbom-generator/issues/218 (possibly a duplicate)

Assuming I’ve understood the code properly, this should help resolve this error: https://github.com/opensbom-generator/spdx-sbom-generator/pull/266
