Can't figure out proper syntax for config.yaml file despite checking everywhere

[harryfine]

I'm trying to back up my immich docker database and assets using Borgmatic, both in my Synology in docker containers. I thought I was following the new format for commands, but I'm getting this when running the backup using the config file below:

/etc/borgmatic/config.yaml /etc/borgmatic.d /root/.config/borgmatic/config.yaml /root/.config/borgmatic.d: No valid configuration files found

summary:
/etc/borgmatic.d/config.yaml: Error parsing configuration file
An error occurred while parsing a configuration file at /etc/borgmatic.d/config.yaml:
At the top level: Additional properties are not allowed ('monitoring' was unexpected)

Please note that this is not the borgmatic site, but "only" about borgbackup.

As noted above, this is the borgbackup repo - the file you are debugging is a borgmatic configuration file, and borgmatic is a separate project with its own support channels.

The error itself is a borgmatic schema question: Additional properties are not allowed ('monitoring' was unexpected) plus the old location: section indicates a config written for borgmatic's pre-1.8 schema. borgmatic 1.8.0 flattened those top-level sections, so source_directories, repositories etc. now live at the top level instead of under location:.

Please take this to borgmatic:

Closing here as off-topic for borgbackup.
