Catalog API Subcatalog error?

Hello, i am using the HTTP Catalog API to search up hats and music for my admin commands, but they have stopped working.

i have noticed that the Subcategory feature of the catalog API has stopped working,
and when i have checked on my browser,
roblox says “Category subcategory selection not supported.”

i have looked for a way to replace it but all i could find was a value to switch between searching models and the avatar shop.

is there a replacement to the Subcategory value or a different way to search up specific types of items (ie hats and nothing else) ?

EDIT: problem solved, i realised i could no longer use both Category and SubCategory on the api at the same time.
