Firefly video generator does not work

I am trying firefly for the first time in the Google Chrome browser.   Here is my "enhanced" prompt:   "A man in a small, weathered rowboat rows frantically as a massive whale approaches, its form looming in the misty, photorealistic background. The camera follows the boat from a low angle, capturing the man's determined but futile effort to escape. As the whale engulfs the man and rowboat, the camera dives into the whale's mouth, showing the man's terrified face before the whale closes his mouth and disappears into the depths. The overall scene is dramatic and suspenseful, with the whale's powerful presence dominating the frame. The video is shot in a photorealistic style, emphasizing the raw and intense moment of the encounter."   I have tried three times and it gives me the same error message:  "Can't load.  We can't display the generated video.  You can edit and try again."

So - I guess it doesn't really work?
