Error logs
No response
Hello, I can't reproduce this on Linux at least. I remember something like this happening in the past, though. Mermaid having infinite cycle or something. Unfortunately Trilium can't catch such Mermaid bugs due to lack of isolation.
How can I recover from this? I'm currently facing a mermaid hang, I tried to open it in the browser and the tab hangs, desktop app hangs, i can't use trilium now :/
Trilium may have a backup for you that you can restore from. See here: https://github.com/zadam/trilium/wiki/Backup#restoring-backup
Alternatively, you can open the database manually and delete the revision or note specifically, if you're able to find it
jesus christ...
how come other apps with embedded mermaid dont suffer from this
Edit: i restored the backup from my desktop app, killed the internet, deleted the old version of the node, restored internet, synced, and deleted the note again without opening it. That saved me from losing any other work.
Edit 2: Don't do the above. Was unable to sync afterwards, had to delete everything and re-import...
@Alumniminium Do you know the mermaid diagram content?
I can't reproduce this on windows desktop when using the sample mermaid code from @gao-feng
Ok, if this happens to you again, or if you can reproduce this, please try to capture some logs or additional information so we can investigate further.
Hello, sorry for this bad experience. The way to recover from this problem is described here: https://github.com/zadam/trilium/wiki/Troubleshooting#broken-note-crashes-trilium
