Hi, I downloaded Kerr_Schild.ipynb at
https://luth.obspm.fr/~luthier/gourgoulhon/bh16/sage.html
It complains about JSON formatting.
A previous version of Kerr_Schild.ipynb (date?) works. for
sage --notebook=jupyter Kerr_Schild.ipynb
Attached is a terminal output. I included everything since I have been
burned by throwing "irrelevant" output out. It does open the browser to
a login but barfs after the login with a rectangular JSON complaint.
It's reluctant to be copy/paste but I can do a screen capture if wanted.
jupyterlab has a similar characteristic; passing old and failing new
download with the failing screen
File Load Error for Kerr_Schild.ipynb

NotJSONError("Notebook does not appear to be JSON:
'\\n\\n\\n\\n\\n\\n\\n\\n\\n<!DOCTYPE html>\\n<htm...")
xxxx's to protect the guilty
