@SylvainLegrand What steps, precisely, lead to this error?

[SylvainLegrand]

Nothing in particular, I just try to open some documents.

I'm seeing a similar issue, using the Collabora version built into the current NextCloud snap version (27.1.6snap1)

Essentially, the first time an ODT document is created, any content saved will be lost. This includes when manually choosing to save, which gets the graphical feedback that it has succeeded. Once the document is closed and opened, it will be blank and there is no historical copy with data.

If I create the ODT, save, close, and then re-open then all subsequent saves seem to work as expected.
Perhaps there's some issue that doesn't properly associate a reference/ID to the newly created file?

I also note that @SylvainLegrand is referencing something in /mnt. Is your nextcloud+collabora instance using external storage (network or USB etc) of some sort? Maybe it's related to a mounted storage volume (which my instance similarly uses).

I'll also add that I am using Debian (rather than Ubuntu) as my base, and that I also saw this when using a Docker container which is actually one of the reason I decided to see if the Snap behaved better.
