Problem: An extractor container was still running when FACT was started (maybe FACT was not shut down cleanly last time)

Solution: Stop all Docker containers of fkiecad/fact_extractor manually before starting FACT Simply run docker ps to find all running containers and look for all instances of fkiecad/fact_extractor. Now run docker stop followed by all container IDs of fact_extractor containers.

Error:

ImportError: cannot import name 'uia_username_mapper' from 'flask_security'

Problem: FACT was installed without virtual environment (venv) and has conflicts with Python packages installed through apt

Solution: Create a venv and activate it (see https://docs.python.org/3/library/venv.html)
