No problem! I’m happy to help.
It’s because you must use a proxy to access the Roblox Web API through Studio since you cannot access it directly.
Most use roproxy though its typically recommended to host your own proxy instead, which is what I do.
If you want to use roproxy, replace the “roblox” part of the base endpoints you’re using with roproxy.
Example: groups.roblox.com would become groups.roproxy.com
