My partner has their own Nextcloud instance on their own server, and they're sharing their photos with me using the federated shares system that Nextcloud provides.
Using the generate-all command, previews for files shared in this manner are generated just fine. However, when a file in a share is changed, or an entirely new share is added, no new previews seem to be generated using the pre-generate command.
After some investigation, it seems that no entry about the newly added/changed file is even added into the oc_preview_generation table, which explains why no previews are being generated. Though I can't be sure, since I have little experience with the Nextcloud API, it seems like the NodeWrittenEvent that the preview generator listens to isn't being fired for files in federated shares.
