Operating System is part of the dedup key; as it already was in the plugin. As already said, we need a way to reproduce on a fresh GLPI instance, so...

Not reproducible on our side. Feel free to reopen with a reproducble use case on a fresh GLPI latest stable release installation.

See #17821 and give feedback on proposed solution.

Shoudl be fixed as of https://github.com/glpi-project/glpi/pull/19772

Masbe should we just inform users that it's not a god practice? For now, the main problem is we do not have any existing alternative to propose.

Check GLPI logs. Also remember to activate inventory, and check relevant configuration.

> _It seems to have been deactivated 8 years ago, but I haven't found the reason?_ No idea neither. Seems it has been added on https://github.com/glpi-project/glpi-inventory-plugin/commit/701aad61f94f747541fe6861128d7100001324a3; maybe @orthagh remembers why...

This seems rather an agent issue than a plugin one; please open a discussion on agent repository.

I think it's not expected to get a null value at this point. Taskjob itself is probably incorrect. Was it updated from a previous version, or created recently?

Check the `json` column of the `glpi_plugin_glpiinventory_deploypackages` table; as far as I understood, this should always contains a valid JSON, and you have a null one.
