Tools fails to run

I've installed the tool as per documented process: pip install -r requirements.txt
However at first use, the tool immediate fails:

python .\spdxmerge\SPDXMerge.py --docpath .\files --name Reporting --version 3.0.0.0 --author "Raymond Kloprogge" --email raymond.kloprogge@philips.com --mergetype 0  --docnamespace "https://philips.com" --filetype J

Reproduce the reported command with Python 3.13, then start in spdxmerge/SPDXMerge.py and follow read_docs in spdxmerge/utils.py into the spdx_tools parser. Check the input file that triggers the None value and whether the installed dependency versions are involved. Done means the command completes successfully or reports a clear, actionable validation error.
