Microposts do not appear in the Mastodon profile

Hey @ostermeiernet 👋

If “micropost” is a custom post type, have you enabled that post-type for federation in the ActivityPub settings?

So I would assume that this has nothing to do with the microposts plugin. I would close this issue here and move over to the ActivityPub plugins forum.

I think we have to bring the issue back to this forum 🫣

You are using a very generic sanitize_micropost_content filter, that simply checks if the $_POST has a post_type=micropost but you do not check if the content_save_pre is really run on a micropost content. So every other post that is saved in the same process will also updated by sanitize_micropost_content and that breaks our ActivityPub JSON.

Can you somehow check if the content is really from a micropost?
