Error while generating SBOM

In a somewhat complex project with subprojects the generation of the SBOM lead to the following error:

* What went wrong:

Unfortunately I'm not allowed to share the project and couldn't recreate with a smaller project. I am aware that this might not be very helpful for the solution of this problem, but at least wanted to give a heads up that there might be a problem.
