Notebook becomes blank/"empty" - JupytextContentsManager.get() got an unexpected keyword argument 'require_hash'")

[bjornarfjelldal]

Using current latest everything (JupyterLab 4.3.2, Jupyterhub k8s 4.0.0 (5.2), jupytext 1.16.4). RTC enabled. Datascience base image (lab-4.3.2)

On certain notebooks, this error is thrown in the Log when opening and/or saving it:

[json:notebook:2c141ddc-2c27-4428-9db4-6e8e88286692] : Error saving file: jupytext-error.ipynb
TypeError("build_jupytext_contents_manager_class.<locals>.JupytextContentsManager.get() got an unexpected keyword argument 'require_hash'")

And it will in the end either not load (blank notebook) or only show the first 4 cells and not expand to the rest.

Ideas, anyone?

Interesting, possibly the argument becomes mandatory. Can you give a try at this development version and let me know how it goes?

Impressively fast answer, @mwouts ! Looks like this works! What also works is to not include RTC/jupyter_collaboration on the current 1.16.4 version (but we would of course like to enable that)

Thanks for your feedback! I have just merged #1202 and will now release Jupytext 1.16.5, however using both Jupyter collaboration and Jupytext is something brand new and untested - please let me know how it works. Thanks
