Error message

Video is still processing (status: {status}). Please wait and try again.

What it means

State guard while extracting a video URL: the task has not finished — its status is a pending/processing state — so no output URL exists yet; the caller is told to wait and retry rather than treating it as a hard failure.

Solutions

1. Poll again after waiting; the video is still processing.
2. Increase timeout if using a blocking call.

Example fix

# wait, then retrieve the video again with the same task id.
