Thanks for the report and the PR @jimjag
See my comments below on why we cannot update fingerprints just yet, as we want to continue to support python3.9

We can conditionally update fingerprints based on python versions like we do for click, attrs :

scancode-toolkit/setup.cfg

Line 73 in d171a74

click >= 6.7, !=7.0, !=8.1.8;python_version<'3.10'

Could you update the PR accordingly so we can check if the tests pass allright?

We cannot upgrade fingerprints just yet, because they have removed support for python3.9, see https://github.com/opensanctions/fingerprints/blob/8eea92ff357e080c6c8bb0807352e7b5f83d9c14/pyproject.toml#L19C1-L19C28
This is not EOL yet: https://endoflife.date/python

Also why the tests are failing because we test and support python3.9.

Note also as mentioned in #4493 (comment), fingerprints is now unmaintained.
So we would want to consider switching to rigour in the future.
