I would recommend you to always run you importer/improver if you have made a importer you should register it under importer only same with improver and some useful commands are python manage.py import --list this would return the list of all registered importers in cli same with improver python manage.py improve --list. Then after this to run a particular importer you can run python manage.py import REPLACE_WITH_IMPORTER_NAME and for improver you can run python manage.py import REPLACE_WITH_IMPROVER_NAME. If you want to run all registered importer or improver you can have python manage.py import --all or python manage.py improve --all respectively.

Rest I have to take a look on you code in order to find out what could be the possible error.

One error is sure that in line 49:

url = "https://raw.githubusercontent.com/anchore/nvd-data-overrides/main/overrides.yaml"

this url is returning 404 Not found which can be also be seen in the logging.
