examples datasets are broken

[seralf]

Hello,
following the instructions provided on the editor section:
https://github.com/mlcommons/croissant/tree/main/editor

After I started the editor application locally, and tried to load one of the existing example datasets, I got this error:

Sorry, it seems that the example is broken... Can you please [open an issue on GitHub](https://github.com/mlcommons/croissant/issues/new)?
