The logs from this are already cleared on my server, but when I sent a private message (standard Create/Note with a single recipient who also has a Mention in the tag property) from my custom software to my account here, I received a 500 error saying something like “cc is not iterable” (though I don’t know the exact phrasing). When I included cc as an empty array, it started working. Not sure whether it was missing on Create or Note, maybe it was both.

    @freamon Create(ChatMessage) is not part of ActivityPub. From my light research online it is something added by a Pleroma extension and possibly supported by Lemmy.

    NodeBB will automatically slot received non-public notes as chat messages.

          @julian I’ve added support to PieFed to successfully receive Create / Note as a PM from NodeBB.

          From Nutomic’s PR, it looks like you’ll continue you get Create / ChatMessage from them, as also you will from PieFed. This currently fails, as I guess that it converts them into a Create / Note, but then complains of there being no ‘cc’.

          It doesn’t make sense for PMs to be ‘carbon copied’ to anyone, so I’ll raise an Issue at your repo.

            @freamon thanks! Happy to look into handling Create(ChatMessage)… I think the error aside, NodeBB would drop it anyway since ChatMessage isn’t an expected post type.

              @julian Oh, I’ve just realised I read Nutomic’s PR the wrong way around. After 2.0, you’ll start getting Notes from them. If ‘ChatMessage’ processing isn’t worth handling by NodeBB, I can change PieFed to send you Notes instead.

      @julian Oh, right. Thanks. But yeah, it’s what Lemmy (and PieFed) uses, so I just assumed it was part of AP, and never looked into it any further.

      I was thinking while typing this “I bet that means that chat messages from NodeBB to PieFed will fail”, which I just tested, and sure enough they do (I’ll make an Issue for it on PieFed’s repo).

        Ah, that’s unfortunate. When NodeBB sends a chat message out, it is just a regular Note with the recipients directly addressed, with no as:Public pseudo-user.

        So as long as PieFed handles mentioned-only notes the activity should be processed…

          @julian It currently doesn’t. If someone is Mentioned, the assumption is that it was part of post / comment in a community, and it fails because it can’t find the community. I know that, for Lemmy, if you Mention someone in a comment, and they don’t have a copy of the community (or they do and there’s no local subscribers to it), then it will reject it. I don’t know what it does if there’s no community at all (I’ll figure out a way to test it, on a server I can control).

            @freamon Update: no, Lemmy doesn’t understand them either. It rejects Create / Note without a community with the usual “did not match any variant of untagged enum AnnouncableActivities”
