API works on original Space, but not on mine cloned (same code)

Hi, I’m trying to solve this for hours by now, I cloned a Space (Voice Cloning - a Hugging Face Space by JKLUCY99) which when I click on the Use via API shows all the commands and the API works normally, but on mine cloned space, without any change, doesn’t work. I tried to upgrade to a paid hardware (T4) and didn’t work whatsoever.
What I’m doing wrong? The space is public, but nothing seems to work. any help is appreciated. thanks!

Hi @vettorazi ! What was the stacktrace you got from the api call?

Nothing. it shows like it the endpoint doesn’t exist, and when I click on the ‘Use via API’ button on the bottom, I see nothing.
