I've noticed that when I do a World Export (for backups) the contents of my Notebooks do not make the export, all there is is a json file that is a shell without any notes. I've tried full exporting (the whole World enchilada), I've tried exporting only the Notebook section, nothing works. I get a 1 KB json file that apparently points to the content, but it's not there, not a single note. As WA is my novel series "bible", it would be devastating to lose any of this work.

In the Export World screen, under the world I want to export (I only have one, so this isn't hard)
- I make sure I have the items I want exported selected (generally all of them)
-Reset (so I can get a new export)
- Start
-When it's done download
- Then I extract the files
- I drill down to the notebook file
- I get the following:

"id": "141ebe61-c744-4a32-b155-733a0cca6a71", "title": "Den-Aronel notes", "slug": null, "state": null, "isWip": null, "isDraft": null, "entityClass": "Notebook", "icon": "fa-solid fa-notebook", "url": "https://www.worldanvil.com/notebook/notebook/141ebe61-c744-4a32-b155-733a0cca6a71/load", "subscribergroups": , "folderId": null, "tags": null, "updateDate": null, "creationDate": { "date": "2023-01-24 05:39:09.000000", "timezone_type": 3, "timezone": "Europe/London" }, "color": null, "weight": 1, "isSelected": 1, "editor": "code", "activeNoteId": "7a1c9d76-3d9f-49f4-8c0e-47882be3ac81", "isEditable": true, "success": true }

That's it. No content, just the shell and the link to the content.
