Traceback (most recent call last):

Fixed in #61

I know how to fix it
but docker image and github code still old
in requirementa.txt
flask==1.1.2

error:
2024-01-17 18:34:53 ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.8/site-packages/werkzeug/urls.py)

Fixed by modifying Dockerfile in docker/events-api:

FROM python:3.8-slim

COPY requirements.txt /tmp/requirements.txt
RUN pip install -r /tmp/requirements.txt && rm -f /tmp/requirements.txt
RUN pip uninstall -y Werkzeug && pip install Werkzeug==2.3.6

COPY app.py /

EXPOSE 5000

ENTRYPOINT ["python"]
CMD ["/app.py"]
