For future reference, you should copy and paste your code instead of screenshotting it as it makes it easier for everyone to change and make modifications.
The reason why you’re getting a 404 error is because the endpoint:
"https://api.roproxy.com/universes/get-universe-containing-place?placeid=12840793936"
doesn’t exist.
This is likely because roblox retired the https://api.roblox.com endpoint last year, and thus, it also doesn’t exist for roproxy.
As an alternative, I assume you would want to use this endpoint instead:
"https://apis.roproxy.com/universes/v1/places/12840793936/universe"
and the key for the UniverseId is universeId, not UniverseId.
