lemmy.world API for communities list returns a page of results even if no such page exists, behaving different from other version 0.18.3 servers

curl 'https://lemmy.world/api/v3/community/list?type_=Local&sort=Old&limit=1&page=250000&show_nsfw=true'

Returns a result for page 250,000 - and if you edit that number +1 it still returns the same final item in the list. Does this on all the sorts I tried. I am not getting this behavior on lemm.ee or lemmy.ml

With page limit at 50, it ends up returning the final same list of 50 no matter what page number you increment past the final page. This could be causing some front-end apps to endlessly load the list.

the lemmy-ui interface seems to be having the same problem: https://lemmy.world/communities?listingType=Local&page=250001

Is this really limited to lemmy.world or is it a general problem with lemmy? If this also happens on other instances, then it should be reported on GitHub.

- I am not getting this behavior on lemm.ee or lemmy.ml
  
  To quote OP. I also tried it on feddit.nl (which is running 0.18.3), which returns an empty array, as you'd expect. On lemmy-world, the result you get for page 250000 is the same result you get for page 1 (the Fediverse community)

any updates on when this will be fixed?

- it's exclusive problem to lemmy.world's DDOS prevention attempts as far as I know, so no idea.

  I'm able to reproduce it on lemmy.ml or lemm.ee so it must be a bug introduced on lemmy v0.18.4.
