[...] I checked out the Mastodon source code and searched for the error message. My Ruby-skills are limited, but it looks like Mastodon expects the type "Account".

I dont't understand what Mastodon expects from me. Any hint would be highly appreciated.

In the meanwhile I'll give https://activitypub.academy/ ad try ...

@achim @silverpill no, I think Mastodon accepts `Person` just fine.

@achim @silverpill you either need to provide an URL to the key itself, with type "PublicKey", and a link to "Person" that is the "owner", or you can provide the URL of the "Person" with an URL fragment "main-key", and your person has to have a "publicKey" property.

@evan Thanks for your response. @silverpill already mentioned the "main-key" fragment. Is that documented somewhere?

I had an implementation that returned just an object of type "PublicKey" if the "./key" endpoint is called.

I checked what I get back from Mastodon if I call my profile with the "main-key" fragment. The result is the full profile.

So should I either refer to the profile url with the fragment and return the full "Person" OR [...]

[...] use a dedicated url (i.e. mine with an appended ./key) and just return an object of type "PublicKey"?

@evan @silverpill

@achim @silverpill I'm rereading the book section on public keys, and it looks good. Do it like that!

@achim @silverpill yes, it's documented in my book.

@achim @silverpill So, here's a minimal example of a key object:

@achim @silverpill And here's the corresponding person object:

@evan I read that section and implemented the preferred version, not the Mastodon one. That did not work, but I might got confused by other mistakes I made. Will give it another try. Thanks for your help!
