Vidu API request failutre

[CrashSensei]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

Open the provided Vidu Text-to-Video API template. Enter a prompt. Run the task and get a video.

Actual Behavior

I receive a 403 response. However, when I attempt to access it via the URL directly it succeeds.

Steps to Reproduce

Choose the Vidu Template, enter text, and hit run.

Other

I have not done extensive testing due to the cost and the quality of the generated video. But of the two times I have use Vidu it has happened both times. Perhaps, if there is a 403 response then it could wait 5-10 secs and try again.
