None of my spools are showing on the filaments page, and adding new ones literally doesn't do anything. This has been an issue for a few days now. There were around 20 in there working just fine for a few weeks, and then one day POOF, gone. Adding looks like normal but after saving, there's still nothing.

As far as I'm aware I have... Also it wasn't right after an update, it was randomly one day last week right after adding a couple of new spools. It was all there and working fine, and then I went back to the filaments page a few minutes later and suddenly nothing.

Again, you need to be more precise.

You updated from version to version?
How did you upgrade to the latest version?

Also please

Enable debug logging
Restart Bambuddy
Add aa spool to inventory
Upload debug logs

Like I said, it wasn't in connection to an update! It was running fine and then suddenly it just wasn't working after adding a couple of new rolls.
Everything is pulled via portainer (re-pull image and redeploy), and I usually have it pull from daily. Updated to the latest version in hopes that it would fix this issue, and sent the bug report in when it did not.
As for the logs, I added a spool/replicated the issue fully (with recording) when submitting the report. So the logs sent with the report is apparently all it logs when adding a spool. But of course, I'll try to find some time later to do that.

Actually, I did enable debug logging and followed the instructions exactly. As you can see in the logs it even says "2026-04-21 10:26:28,540 INFO [backend.app.api.routes.support] Log level changed to DEBUG"

The screen recording is NOT from when debug logging is on, they are separate. I added it after to give you more info.

One would think so, but the logs I sent are literally what it logs when in debug following the wiki instructions:

1. Go to System Information page
2. Find Support & Troubleshooting section
3. Click Enable to turn on debug logging
4. A banner appears across all pages showing debug mode is active with a live timer
5. Reproduce the issue you want to report
6. Click Download to get the support bundle

In the support package I sent, after "2026-04-21 10:26:28,540 INFO [backend.app.api.routes.support] Log level changed to DEBUG" I went straight to the filaments page, tried to add a spool, and then went back to the system. information page and clicked download on support bundle. What I've uploaded is that download. 😕

No logs....hmmmm.....

Please do the following:

cd /opt/bambuddy/frontend && npm i && npm run build && sudo systemctl restart bambuddy && tail -f /opt/bambuddy/logs/bambuddy.log | grep -v "error|warning|failed"

Reload page, add spool and check backend and browser logs.
