    Invalid type error when parsing metadata for packages

    I just wanted to try this out but got this:

    $ nix run "https://flakehub.com/f/louib/nix2sbom/0.1.66.tar.gz" -

  • Error:

    Error: "data did not match any variant of untagged enum PackageMaintainers at line 2361 column 7"

    Saw your flake on FlakeHub and thought I would give it a go. I added it to my config and tried running:

    nix2sbom --current-system

    and I got the following error:

    [00:00:00.000] (7f28fe0877c0) INFO   Getting the derivations from the current system.

Error: "data did not match any variant of untagged enum PackageMaintainers at line 2361 column 7"

    I tried some more things and got the same or similar looking errors:

    campground-nvim and vault-secrets are flakes of mine, the nvim one is based on nixvim and the other is a simple shell script flake I was playing with the other night.

    I very well might be doing something dumb, because I only marginally know what I'm doing. So if I am way out in left field let me know..

    For example, packages coming from cargo should use the cargo scope, packages from npm the npm scope, etc. Only packages that are not coming from a package manager should use the nix scope.

    Implement filtering by dependency type

    We could filter the dependencies by type (build-time VS run-time), and add a CLI option to only generate the SBOM for the build-time or run-time dependencies.

    Update CyloneDX version to 1.5

    The project is currently using the 1.4 version, but the 1.5 version is already available and is supported by the serde_cyclonedx crate. We could also support both and add a CLI flag to toggle between 1.4 and 1.5.
