Artifact store permission errors running mflow_example.ipynb

[julien-flack-adnav]

All services start successfully and the MLFlow UI can be seen on http://127.0.0.1:5001/ and Jupyter notebooks on port 8888. However, when I attempt to run the included notebook mlflow_example.ipynb I get the error below. Worth noting that the metrics and parameters log ok and are visible but the artifact store is not working ... any help appreciated.
