Unexpected Error While Uploading .HTML Notebook on Zindi
Help · 3 Nov 2025, 05:37 · 3

I recently created a Python notebook and converted it into an .html file on Kaggle. I tried to upload the .html version of my notebook to Zindi for the challenge, but I’m encountering this message:

“An unexpected error has occurred during scoring, our team has been alerted to this issue.”

Here’s what I did:

  • I developed and tested my notebook on Kaggle.
  • I used the standard Python environment and exported my notebook using: jupyter nbconvert --to html my_notebook.ipynb
  • The file uploads fine on Zindi, but as soon as I try to view or submit it, I get the error message above.

I’m not sure if:

  • if the conversion from .ipynb to .html causes a formatting issue, or
  • if there’s a temporary scoring system error on the site.

Has anyone else experienced this issue? If anyone from the Zindi team is reading this — could you please confirm if .html notebooks are supported for upload and viewing? @zindi

Hi @MuhammadQasimShabbeer, we are looking into the issue. However, I would like to point out that the idea was really to use Observable notebooks which are more suited for data storytelling. Are you able to reproduce what you did in an Observable notebook with the time left ? On the challenge Info page, the instructions under "Submission Format" describe how to properly convert an Observable notebook into an HTML file.
