Sometimes an API request returns {"comments":[]} and {"posts":[]} respectively, for a post and community, where posts and comments show up on the web frontend. Is that happening to any of you too? How do I handle it?
Edit: did some more testing, it’s most definitely a federation issue. If I query the instance that the post was made on for the comments, everything works fine. If I query my home instance, the result comes back empty.
Edit 2: As always, just after publicly showcasing my lack of programming abilities, I discover it’s been me the entire time. Make sure to await promises and to fetch posts from the correct instance, guys.

Oh, I ran into that. There is a post on !lemmycode@lemmy.ml even.
You need to set the type_=All on fetching comments for a community that isn’t originated on your local server. You can just use that parameter when fetching comments from any post.
Pretty sure it didn’t work, but I can’t replicate it right now. Will need to see if it happens again
Lol, I was gonna say I’ve never experienced this before
I’ve had lemmy_helper crawling posts looking for missing comments for the same post on different servers, thousands of posts, and I haven’t seen this yet. Lemmy.ml is the most unstable server - it ever returns an HTTP status problem or some error message.
To be clear, I checked twice that my limit and page parameters are correct. I request page 0 with limit 10 and get nothing, while the post counts clearly say there are multiple comments and while the web interface shows them normally. Very weird

Lemmy API starts at page 1, page 0 is invalid?
curl "https://lemmy.ca/api/v3/post/list?limit=2&page=1"
curl “https://lemmy.ca/api/v3/comment/list?post_id=648889&type_=All&limit=2&page=1”page=0 returns {“error”:“couldnt_get_posts”} (or comments)
I meant page 1, sorry
