When someone replies from Mastodon (or any other fediverse app) to a post published from Discourse using the ActivityPub plugin, the reply does not show up in Discourse.
You can see an example post here: https://forum.internet-czas-dzialac.pl/t/nowy-test-fedi/2718
And a reply to from Mastodon here: https://toot.kuba-orlik.name/@kuba/114257160278213301
The reply does not show up in the Discourse interface. I'm using the latest version of the ActivityPub plugin (4db5006) and a self-hosted Discourse on a VPS.
The errors that appears immediately after posting a response on Mastodon says:
