Hi, so I was testing the CustomTypes API and I keep getting a 404 in the cURL requests and also a JS implementation of it.

Thanks @Phil, that makes sense now πŸ˜ƒ, I thought it might have been the reason Regarding where it is activated on Slice Machine repositories automatically, is that for new ones, or older Slice Machine repositories? ---
