attempt to index field 'kernelspec' (a nil value)

I am trying to open an .ipynb file in neovim but I get the following error:

Error executing vim.schedule lua callback: vim/_editor.lua:0: nvim_exec2()[1]..BufReadCmd Autocommands for "*.ipynb": Vim(append):Error executing lua callback: ...cal/share/nvim/lazy/jupytext.nvim/lua/jupytext/utils.lua:17: attempt to index field 'kernelspec' (a nil value)

This comment mentions that it is because there is no kernelspec attribute in the notebook.

I am not sure how to provide that or if it's a bug?
