RuntimeWarning: invalid value encountered in cast
I am running this work flow in runpod.io. But at the end of work flow the video generated is corrupted, there is black colored video with just voice.
I tried everything, even suggestions from Claude Opus 4.7. But still same error.
Anyone has faced same issue.
Below is the models used:

In the console log I could see below lines:
