Private threads on Hubzilla I started a private thread between my account and a test actor. The root post was delivered to me (as an Add/Create/Note) and all the objects in the message have: {   "context": "https://zotum.net/conversation/2ffbd4e4-6197-4922-98ec-bedd4108679d",   "contextHistory": "https://zotum.net/conversation/2ffbd4e4-6197-4922-98ec-bedd4108679d",   "to": [     "https://zotum.net/lists/17bb4e2e-3149-4803-ad61-b8b8357af703"   ],   ... } But I can't dereference either of these URLs, or any of the object IDs, not even with a signed request. In particular, I can't dereference the to URL, which means my test actor can't reply to the thread. :( Should I expect to be able to fetch these? I would have thought a signed GET would work, but it seems not. Is it worth trying to set up a local Hubzilla instance to test against? I can do this, but I thought asking first might be a lot easier. #ActivityPubDev #FediDev
