Got the same bug. Tried with the investigation report template offered in the documentation. Also, tried safe mode and still got it.

I’ve reproduced the bug described in this issue and identified the root cause in the docx_generator package, specifically in /opt/venv/lib/python3.12/site-packages/docx_generator/globals/picture_globals.py. The error occurs because the code attempts to access the name attribute of a string object in the PictureGlobals.init method, which is not valid.

Temporary Workaround As a temporary fix, I modified the Dockerfile to patch the problematic line during the image build process. Here’s the change I added to the Dockerfile in the compile-image stage:

COPY source/dependencies /dependencies
COPY source/requirements.txt /

RUN pip3 install -r requirements.txt

#Fix report generate
RUN sed -i 's/self._available_alignment_values.append(member.name)/self._available_alignment_values.append(member)/' /opt/venv/lib/python3.12/site-packages/docx_generator/globals/picture_globals.py

###############
# BUILD IMAGE #
###############
FROM python:3.12 AS iriswebapp
ENV PYTHONUNBUFFERED=1 DOCKERIZED=1

COPY --from=compile-image /opt/venv /opt/venv

This change replaces member.name with member, ensuring the alignment values are appended correctly. After rebuilding the Docker image with this modification, the report generation worked without the AttributeError.

This is also fixed by https://github.com/dfir-iris/docx-generator/pull/4 from the dependency, but this hasn't been folded into IRIS proper yet.
