MissingIDFieldWarning warning in SysML jupyter notebooks may cause an issue in the future

[KlausGPaul]

Description

When creating a new SysML notebook, the console displays the following warning:

/home/.../anaconda3/lib/python3.10/site-packages/notebook/services/contents/manager.py:353: MissingIDFieldWarning: Cell is missing an id field, this will become a hard error in future nbformat versions. You may want to use `normalize()` on your notebooks before validations (available since nbformat 5.1.4). Previous versions of nbformat are fixing this issue transparently, and will stop doing so in the future.
  validate_nb(model['content'])

Environment

Freshly installed ubuntu 24.03 LTS minimal for ARM, running in a virtual UTM machine on a Mac Arm host. Environment

• Anaconda3-2024.02-1-Linux-aarch64.sh
• openjdk 11.0.15-internal 2022-04-19

Impact

None at this stage as this is a warning only, but may cause an issue in the future.

Workaround

I found https://stackoverflow.com/questions/75632445/anaconda-jupyter-notebook-and-missingidfieldwarning and used the proposed fix:

import nbformat

with open("problematic_notebook.ipynb", "r") as file:
    nb_corrupted = nbformat.reader.read(file)

nbformat.validator.validate(nb_corrupted)
# <stdin>:1: MissingIDFieldWarning: Code cell is missing an id field, 
# this will become a hard error in future nbformat versions. 
# You may want to use `normalize()` on your notebooks before validations (available since nbformat 5.1.4). 
# Previous versions of nbformat are fixing this issue transparently, and will stop doing so in the future.

nb_fixed = nbformat.validator.normalize(nb_corrupted)
nbformat.validator.validate(nb_fixed[1])
# Produces no warnings or errors.

with open("fixed_notebook.ipynb", "w") as file:
    nbformat.write(nb_fixed[1], file)
