I noticed there are a few specced lexicons that are unpublished. From what I've found these are:
- social.grain.comment
- social.grain.comment.defs
- social.grain.graph.block
- social.grain.graph.muteActor
- social.grain.graph.unmuteActor
- social.grain.story
- social.grain.story.defs
Seconding this! My galleries were being denied with an unhelpful error message in the Android app - turns out the photo writes were being denied at my PDS because alt text is required in the published lexicon and I didn't have alt text for my pictures (shameful, I know).
It looks like the server believes alt text is optional, and it just gets 400 error from my pds, and that surfaces in the app as "The server had a problem".
