I meant "collection of activities" should be returned.

Actually I don't see "conversation" in ActivityPub spec. But there IS "context" there: https://www.w3.org/TR/activitystreams-vocabulary/#dfn-context And I think that the "context" URL should be used to point to the "conversation" page ?!

In the example response shown in https://todo.sr.ht/~tsileo/microblog.pub/121 the "conversation" (and the same for "context") URL is this: https://andstatus-testing.microblog.pub/contexts/8312ee2f4b474248b6fad147b80fdcf8 It points to 404 page. If accessed via ActivityPub, the request returns NOT_FOUND (404) also.

Expected: "conversation" URL should lead to the conversation:

• Web page if accessed via Browser
• and pages collection if accessed via ActivityPub

We got rid of "Mastodon API" in AndStatus: it was used during OAuth 2.0 registration and logging in only! Basic features starting to work... Now starting fixing actually ActivityPub C2S bugs. I've just created the issue here: https://todo.sr.ht/~tsileo/microblog.pub/121

I'm testing ActivityPub C2S implementation using AndStatus app ( https://github.com/andstatus/andstatus#readme ).

Expected: According to https://www.w3.org/TR/activitypub/#create-activity-outbox response should be an Activity wrapping a note. Actual result: only a Note object is returned, no Activity.

This causes activities duplication at a client side, as the initial "Create" activity doesn't get an id from a server.

Example: the note https://andstatus-testing.microblog.pub/o/4e6e10825ea0439eb7ee99d773b7a0e4

was sent with this payload:

{
  "@context": "https:\/\/www.w3.org\/ns\/activitystreams",
  "type": "Create",
  "to": [
    "https:\/\/www.w3.org\/ns\/activitystreams#Public",
    "https:\/\/andstatus-testing.microblog.pub\/followers",

  ],
  "actor": "https:\/\/andstatus-testing.microblog.pub",

    ],
    "content": "A note mentioning #Mastodon account @AndStatus@mastodon.social"
