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.

rikudou As far as I understand things, a ‘private message’ in ActivityPub is Create / ChatMessage, not Create / Note. I think NodeBB wouldn’t be the only software to complain if ‘cc’ is missing from either part of Create / Note (although it’s not expected in either part of Create / ChatMessage).

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.

FYI the next Lemmy version will use Create/Note for private messages. You can test it on voyager.lemmy.ml

Private messages and public comments are quite awkward in Activitypub, because the json format looks identical. They only way to differentiate them is to check for the presence or absence of https:...

It seems all of the test instances are down? I get a 502 no matter which of voyager.lemmy.ml, enterprise.lemmy.ml, and ds9.lemmy.ml I try to open

Yes not sure whats wrong there, the server was using a lot of cpu for no reason. Restart fixed it for now, let me know if it happens again.

Voyager still has an issue, but the others seem to work now
