API call GetComments sometimes returns no comments (lemmy.world)

3 comments fedilink hide all child comments

This happens for me on a small number of posts, and is generally repeatable, even when the website shows comments.

For instance, running on lemmy.world, GetPost(id: 290602) tells me the post exists and has 7 comments, as does https://lemmy.world/post/290602

But GetComments(postId: 290602) returns an empty list.

If I run against the original post on 'programming.dev', GetComments(postId: 99912) does show me the comments, but I don't think I'm supposed to be second guessing the federating logic :-)

Has anyone seen anything similar or can confirm they see this same behaviour for this post?

I was running into this. I’ve noticed that some instances seem to have limits to how many comments you can fetch at a time, especially when there is no “limit” or “page” set. Setting “limit” or “page” or a parent id seems to avoid it. The limits for each server might be under getSite(), but if those limits are related to this issue specifically, haven’t tested it

Thanks, that’s an interesting gotcha to watch out for.
