I created a 10-second video, but it failed to generate, and 300 points were deducted from my account. Could you please clarify what went wrong? Task ID: d28lisle878c73cqg9h0 . Is this an issue on my end or a possible bug? Even if I had made a mistake with the prompt, I would expect to receive a static 10-second video rather than just an image in MP4 format. Thank you for your assistance.
