"XMLHttpRequest error code: 400" on dockerised TW5

#1

I am hosting a small wiki with TiddlyWiki5 to document our progress in a role-playing campaign. I love the ability to easily create filtered lists to dynamically create lists of tagged pages. The tw instance is hosted via docker and so far it worked beautifully for our small group and I am reluctant to switch to another wiki (coming from Dokuwiki a few years ago).

TW is hosted with the following docker-compose.yml:

tiddly-symbaroum:
  image: nicolaw/tiddlywiki
  container_name: tiddly-symbaroum
  volumes:
    - /opt/tiddly_symbaroum:/var/lib/tiddlywiki
  ports:
    - 8096:8080
  restart: unless-stopped

There is nothing special in the container’s logs and the following error message is all I get: Sync error while processing save of '$:/StoryList': XMLHttpRequest Fehler-Code: 400

The folder (/opt/tiddly_symbaroum) is writable and the standard user owns the folder. It worked until a few weeks ago and to my knowledge I did not tinker too much.
I also tried spinning up a new instance and the same error is present there, so I can rule out anything plug-in-related or tinkering with the TW files themselves. I tried hosting on Github pages but transferring my old wiki over there would be quite cumbersome.

Any idea what could be the culprit here or if there are better ways of running TW for a group of people?

Hi @Cantello I am not technical enough to answer your question, but there’s recent discussion around the PWA method of using TW, and although it’s not really setup for this, I created a little demo showing that because PWA syncs near real-time at a tiddler level, it makes a pretty good platform to build multi-user on top of if you fully trust each other with credentials.
