Croissant Editor can't load datasets when run from Docker

[pdurbin]

I was told to open an issue...

... so here it is! 😄

I can't seem to load any dataset when running the Croissant Editor in Docker, the first option listed in the README. (It works fine at https://huggingface.co/spaces/MLCommons/croissant-editor .)

In the UI I see "Sorry, it seems that the example is broken... Can you please open an issue on GitHub?" (as above).

From the terminal, I see ERROR:root:'dict' object has no attribute 'split' (as below).

I was trying to load the Titantic dataset but (again), I can't load any dataset.

Terminal output:

$ docker run -p 8501:8501 -v ~/.cache/croissant:/root/.cache/croissant -it mlcommons/croissant-editor

  You can now view your Streamlit app in your browser.

ERROR:root:'dict' object has no attribute 'split'

This is the version I'm running:

$ docker images | grep croissant

This editor seems great, by the way. It reminds me of Dataverse's Data Curation Tool: https://github.com/scholarsportal/Dataverse-Data-Curation-Tool
