What exactly do you mean with parallel federation and queues backed up? There is such a feature but only a single case that requires it, which is federation from lemmy.world to aussie.zone. NodeBB wont be affected by that.

[email protected]

@[email protected] have you tried navigating directly to the url without the preceding @? It isn't required (for NodeBB).

In cases where the category is currently a user, you'll have to put the whole handle into the search box and execute the search, the category will then be migrated from the user.

Not specifically that URL, no. Now I just tried it. It resulted in a deadlock in Postgres.

After restarting NodeBB, I can load the category, though. Maybe some deadlock on initial import of the community.

[email protected]

@[email protected] Mostly what I've observed is significant instances of timing out when trying to find communities on new instances from non-Lemmy-based websites, something that hasn't been notable from Lemmy-to-Lemmy first encounters.

[email protected]

Great to see! Existed to see better interoperability between Threadiverse software! Will be cool to see NodeBB users posting in Lemmy/Mbin/Piefed communities

[email protected]

In principle that sounds like a problem with NodeBB or other platforms you are using. Lemmy doesnt do anything special to fetch remote communities. But if you notice any error responses served by Lemmy you can open an issue.

[email protected]

I just realized that while we now have the ability to browse and follow remote communities, we don't have a page listing communities ordered by popularity or recency... time to add to my ever expanding list

projectmoon

Is it also possible to add remote communities to the main forum list? Or merge them into existing local categories?

[email protected]

Right now you're able to add remote categories to your world page. It's possible that we could allow admins to add remote categories to the forum index, although that'd be something we add later on.

projectmoon

I'm seeing issues with loading remote categories. I can't load the NodeBB bug reports category at all, and for the ActivityPub category, I can find it in my world category search, but I get a 404 when trying to load it. Also can't load [email protected] for example.

It seems the NodeBB development board is the only one really federating for me. Any way I can solve this?

I am running beta2 of 4.3.0.

[email protected]

@[email protected] hmm... could be a bug in the user migration code path.

Can you run your forum in dev mode (./nodebb dev) and try to load some of the categories here in your forum, and let me know if you see any errors in the console?

projectmoon

@[email protected] could not run it in dev mode directly because of docker compose, but did set NODE_ENV to development and got verbose logs. Only thing that shows up is:

2025-05-03T19:35:59.553Z [4567/53] - warn: Route requested but not found: /category/[email protected]

projectmoon

So, this URL does work: https://forum.agnos.is/category/[email protected]

Maybe it has something to do with the activitypub category being a sub-category of nodebb development?

[email protected]

@[email protected] no, that didn't matter. There is no concept of nested categories in ActivityPub yet.

But the issue seems legitimate, I can't access the ActivityPub category from a test Mastodon server either.

projectmoon

@[email protected] I was able to access it from a Lemmy instance. So it is federating, at least partly. But interesting to know that Mastodon has issues with it...

One thing that might be helpful is that NodeBB gives an invalid ID error when trying to follow the category via the sync function in admin settings. Stack trace shows it's the error being thrown when trying to follow (activitypub.js line 43).

[email protected]

@[email protected] thanks, can you try again? For whatever reason the handle-to-cid association was lost, and I'm not sure why. I've manually restored it now.

projectmoon

Yep, shows up now on my end. Maybe check other categories too?

[email protected]

Were there other categories breaking?
