Description

Saving notebook omits widget buffers, even when "Save Widget State Automatically" is enabled.

When saving a notebook with an embedded widget, if you want to share this notebook on a sharing site like notebooksharing.space, you want to fully embed the widget in the notebook. It's my understanding that "Save Widget State Automatically" intends to enable this use case.

The widget I develop, Lonboard, uses binary buffers to transfer data from Python to JS. When I save a notebook with a rendered widget, all widget state except the buffers is included in the saved JSON.

This repo (https://github.com/kylebarron/jupyterlab-save-notebook-state-bug-example) includes a reproduction of this.

If you look at example.json (saved from JupyterLab), there are 3 widgets included in the notebook. The third widget (with "_layer_type": "scatterplot") should have a buffers key but it's missing:

In contrast, if we use nbconvert to run the notebook, we can see that the buffers key is included:

pixi run python -m nbconvert example.ipynb --to ipynb --stdout --execute > example_nbconvert.ipynb
image

Reproduce

This repo (https://github.com/kylebarron/jupyterlab-save-notebook-state-bug-example) has a pixi lockfile and notebook to reproduce.

  1. Clone the repo.
  2. pixi install
  3. pixi run python -m ipykernel install --user --name "$(basename "$PWD")" to initialize the python kernel
  4. Open JupyterLab from the current environment pixi run jupyter lab
  5. Open and run example.ipynb

Expected behavior

Expected the buffers key of the widget state to be saved.

Context

  • Operating System and version: MacOS 14.4.1
  • Browser and version: Chrome 124.0.6367.78
  • JupyterLab version: 4.1.8
