Mastodon/Activity Pub question:
-
My current working theories in no particular order:
- I've missed something about how create activities/notes are constructed which conveys some kind of explicit/implicit content type?
- does mastodon do some form of tiered server trusting when it comes to deciding what to format?
- a text encoding issue somewhere?
What we have learned so far:
- taking the json my service produces and mirroring on another AP service results in mastodon rendering the HTML on the mirrored post - so it unlikely to be an issue with the Note object at least...
- just in case, I've tweaked a couple of things in webfinger, nodeinfo, and http header signing to better align the behaviour that mastodon is has, to no effect.

I have officially ran out of ideas...probably time to take a break....
Request: If anyone who knows anything about mastodon internals has any idea why plain text messages would show fine, but basic html formatted messages would show empty (see above) - I would greatly appreciate any insight.
Edit: Thanks all, This has been Solved! (https://mastodon.social/@sarah@tap.resistant.tech/114644828209750037)

@sarahjamielewis can you share a sample json you're sending?

The note: https://tap.resistant.tech/sarah/posts/1749337528.json (doesn't include the wrapping Create activity, but sending plain text messages work, so I assume the Create activity is OK...I can pull one from the debug logs)

@sarahjamielewis Hey @evan any ideas?
@soatok @sarahjamielewis they've got a list of tags they allow. Could you be using something at the top level that they sanitize out?

@sarahjamielewis Nothing is obviously wrong with it. This is just a guess, but it might be the capitalization on the unicode escapes? Mastodon capitalizes them. Here's a mastodon note that I keep around for regression testing

https://github.com/Letterbook/Letterbook/blob/main/Tests/Letterbook.IntegrationTests/Data/mastodon_post.json@sarahjamielewis I put this together to help with interop testing. It's really useful to have access to mastodon's logs while you're trying to do this stuff

https://github.com/Letterbook/Letterbook/blob/main/Tests/Letterbook.IntegrationTests/Data/mastodon_post.jsonjenniferplusplus@hachyderm.io I think it might be the Unicode escapes too. I don’t think they’re necessary.
