Problem with generate Avatar video with N8N

Hi,

I'm generating videos with HeyGen through N8N, but it gives me an error while creating. The JSON text is correct, but I don't understand what the HeyGen error is. When i go to HeyGen to check the video i found a black project with a red write "error" below, but there isn't any explanation. What is the problem? Gemini told me to check the Id of the avatar and the voice i had use for the JSON text. If you want to check, the id are:

AVATAR ID: de81680b4f474f9098c2bf36c1979a69

Voice ID: c9b884c169964193a728bd99947e18f7
