Jupyter Notebook will not open, just shows JSON.

[jamesdsmith99]

Issue Type: Bug

Double click the jupyter notebook to open in the file browser in the left. Then JSON will appear in the text editor.

The notebook editor still opens when creating a new notebook.

Running python in a Conda environment in WSL 2 with ubuntu.

Thanks for the issue @jamesdsmith99. We have a setting called 'python.dataScience.useNotebookEditor' that either opens the json or the Notebook Editor. Could you check if you have it set to false? That could be your issue.

[jamesdsmith99]

Thanks for the reply @DavidKutu the setting is set to true.

I can't get it to repro on regular windows, I think it only happens on WSL 2. We'll have to discuss this in an upcoming meeting.
In the mean time, please try to right click on your ipynb file and select 'Open in Notebook Editor', that should work.

Thanks, it is worth noting that creating a new notebook does work as intended.

Thanks for your feedback. This issue will be addressed once VS Code adds native support for editing notebooks. Please see microsoft/vscode#91987. You can experiment by using VS Code insiders, which defaults to the new notebook experience.
