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)
The empty render: https://mastodon.social/@sarah@tap.resistant.tech/114644584327450993
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)
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.
@julian ah looks like the webfinger lookup was a little too restrictive (previously it only resolved acct:sarah@tap.resistant.tech), now it resolves other versions including the one you linked
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?
Mastodon/Activity Pub question:
As far as I can tell mastodon posts are expected to have a rich text / html-subset representation i.e. https://docs.joinmastodon.org/spec/activitypub/#sanitization)
I'm writing a tiny activity pub service, mastodon is currently stripping out all html tags when displaying posts from my dev account (see e.g. https://mastodon.social/@sarah@tap.resistant.tech/114643976114333084), plain text posts work fine (see e.g. https://mastodon.social/@sarah@tap.resistant.tech/114643533179472725)
I'm attempting to work out why that is the case, but this is proving to be a hard thing to search for.
