API needs better failure feedback

I mentioned this in the Heygen Hub. I just tried to generate a video and I get this:

Generating video...
Error: Failed to generate video: 404 Client Error: NOT FOUND for url: https://api.heygen.com/v2/video/generate

It worked with the other avatar? I see others are sharing my frustration about this.

I'm close to giving up on HeyGen. Sorry!
