Alright, I became a swift dev for the day because this was driving me crazy and the working test flight builds have expired. Our default json dump was escaping non ascii characters in content. ndb_builder_make_json_str fails as a result. We updated filter.nostr.wine to use UTF-8 instead to align with the NIP.
nostr:npub1t3ggcd843pnwcu6p4tcsesd02t5jx2aelpvusypu5hk0925nhauqjjl5g4 - tl;dr the issue is fixed!
