Describe the bug

Thanks for this great project and for Jupyter Book! Obviously many of the same people work on both projects.

After upgrading to a recent version of this package, I'm getting the error:

Exception occurred:
  File "/opt/conda/lib/python3.11/site-packages/jupyter_cache/cache/db.py", line 62, in session_context
    raise RuntimeError(
RuntimeError: Unexpected error accessing jupyter cache, it may need to be cleared.
The full traceback has been saved in /tmp/sphinx-err-npmhkzbj.log, if you want to report the issue to the developers.
Please also report this if it was a user error, so that a better error message can be provided next time.
A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks!

Reproduce the bug

It seems likely this is a known issue. See jupyter-cache/CHANGELOG.md and the breaking change mention of nbstage and nbproject.

Unfortunately I've got many notebooks that take hours to execute and use R packages that don't produce completely reliable i.e. reproducible results 🙄 (see e.g. Practice: Chp. 14).

I've not found a way to avoid re-execution and so for now I'm planning to attempt to rebuild the cache over a day or two. I'd just like to confirm there's likely no other way around this problem.

List your environment

$ jupyter-book --version
Jupyter Book      : 0.15.1
External ToC      : 0.3.1
MyST-Parser       : 0.18.1
MyST-NB           : 0.17.2
Sphinx Book Theme : 1.0.1
Jupyter-Cache     : 0.6.1
NbClient          : 0.7.4

Welcome to the EBP community! :tada:

@davidvandebunte before you re-execute, I think it should be possible to manually upgrade the database. From the CHANGELOG, it appears that the table name changed, and the schema includes some new fields. I think if we make those changes by hand, we should be in luck.

Thanks @agoose77! As you suggested it wasn't all that difficult:

ALTER TABLE `nbstage` RENAME TO `nbproject`;
ALTER TABLE nbproject ADD COLUMN read_data JSON;
ALTER TABLE nbproject ADD COLUMN exec_data JSON;

The schema doesn't match perfectly: so far I've noticed that read_data should be JSON NOT NULL and the order of the columns is different than in a regenerated cache. Still, this seems to be good enough so far.

Ah, you're quicker than me! For others, I created an alembic project to do this automatically: https://github.com/executablebooks/jupyter-cache-upgrader/tree/main/alembic

As ever, please please please back up the cache before trying this or any other surgery!
