Error: Unsupported nbformat version 5 when opening Jupyter Notebook

[rezadrian01]

I encountered an issue while trying to open a Jupyter Notebook file in the terminal. When attempting to open an .ipynb file, the following error message appears:
File Load Error for file.ipynb: Unreadable Notebook: path_to_file NBFormatError('Unsupported nbformat version 5')
Has anyone else experienced this issue or found a solution?

I've experienced this issue. This error is comes when jupyter processes an empty .ipynb file. If you make the file from the jupyter interface, it should not create a blank file and have something like this:

{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": null,
   "id": "c3a19e18-06bd-4d5a-8a57-17c3cb898830",
   "metadata": {},
   "outputs": [],
   "source": []
  }
 ],
 "metadata": {
  "kernelspec": {
   "display_name": "Python 3 (ipykernel)",
   "language": "python",
   "name": "python3"
  },
  "language_info": {
   "codemirror_mode": {
    "name": "ipython",
    "version": 3
   },
   "file_extension": ".py",
   "mimetype": "text/x-python",
   "name": "python",
   "nbconvert_exporter": "python",
   "pygments_lexer": "ipython3",
   "version": "3.13.1"
  }
 },
 "nbformat": 4,
 "nbformat_minor": 5
}

The temporary fix for this would be to change the nbformat and nbformat_minor values to what I have shown above. You can open it in notepad or whatever you use to edit text files. I think that nbformat needs to be able to process version 5 or the jupyter peripheral responsible for processing an initially empty file and generating the values for these keys needs to change to 4 and 5.
