Hey #ActivityPub friends.

@Edent No, thank you for making this <3

It is served by an instance of your bot? The value of inReplyTo in this document is an empty string, which is not a valid URI.

[edent@mastodon.social]

@silverpill good spot!
I assume if it isn't a reply, the field should be excluded?

Or should it be something else?

[julian@activitypub.space]

@edent@mastodon.social I've learned that it should be excluded altogether, and not a null value

[silverpill@mitra.social]

@julian @Edent Yep

(although I think we should bring back null)

[edent@mastodon.social]

@silverpill @julian @general
Ah, I assume that `cc` should also be null if it isn't copied to anyone?

[julian@activitypub.space]

@edent@mastodon.social :shrug: I was passing null around like candy but some implementations choke on that. In general, tolerance of odd values in cc is well handled, but I would just omit or send [].

[edent@mastodon.social]

@threkk the bot can now send Delete messages. They're processed successfully by Mastodon.social - so I assume they work elsewhere 🙂

Will have a think about editing.

[silverpill@mitra.social]

@Edent @julian It should either be omitted or be an empty array (opinions differ).

[evan@cosocial.ca]

@Edent @silverpill don't use nulls. Just omit it.
