Equip api 404 error

Hi,
I’m getting 404 error when calling the equip and unlock API:

I’m adding a valid x-api-key token to the header and passing a valid asset id. I’m using the following endpoint for the PUT request

https://api.readyplayer.me/v1/avatars/67f5297b3bd3a4368565d14d/equip

Anyone experience the same?
