.. warning:: Manual intervention required
In this bugfix release we fixed a bug regarding the default values of some components
being ``null``. We added a script to fix any forms that still might be affected by these
issues. You should run this script after deploying the patch release, to make sure the
default values of affected components are fixed.
.. code-block:: bash
# in the container via ``docker exec`` or ``kubectl exec``:
python /app/bin/fix_component_default_values.py
