@heathenstorm why you're getting "No username provided" on the shared inbox though, I've no idea.

@heathenstorm that is, configuration changes like that only change what pixelfed serves / pushes from that point in time onwards, but other software may be caching actors, in order to let them know the actor has changed, you need to publish an Update activity on the Actor.

So just setting that configuration value to false does nothing as far as anyone else is concerned, because they've already a copy of your actor document, and they haven't been told it's been changed.

@heathenstorm mastodon is probably caching the actor and doesn't realise that it's changed on the pixelfed side.

So you likely need to dispatch for each actor on the pixelfed server an update to the actor to all servers.

Late night #activitypub interop hacking. Again.

Has anyone else had trouble with the #pixelfed shared inbox?

Seems hits to /f/inbox don't send a username. Worker gives the error: "ActivityHandler: No username provided, skipping job"

Likes from self-hosted #mastodon go to the user inbox, Boosts and Comments go to the shared one.

I disable shared inbox in settings and Mastodon still sends to /f/inbox even though I've refreshed the pixelfed profile.

At least I know why it's happening now!
