ElevenLabs input video does not exist

Error message

ElevenLabs input video does not exist

What it means

Guard in generate_bgm: os.path.isfile(video_path) is false — the input video file does not exist (or is a directory). Checked before any network or proxy work so the task fails fast instead of uploading garbage or crashing later in _create_video_proxy.

Solutions

1. Verify the concat/render step actually produced the file and that the path passed to generate_bgm is the same absolute path
2. Use absolute paths (Path(video_path).resolve()) when queueing the BGM job
3. Check mount points if generation and BGM run in different containers
4. Add an existence assertion right after the render step to catch deletion races early

Example fix

# before
generate_bgm(video_path, output_path, duration, prompt)  # path may be stale

# after
video_path = str(Path(video_path).resolve())
if not os.path.isfile(video_path):
    raise FileNotFoundError(f"concatenated video missing before BGM: {video_path}")
generate_bgm(video_path, output_path, duration, prompt)

from pathlib import Path

p = Path(video_path).resolve()
assert p.is_file(), f"missing input video: {p}"

When it happens

Trigger: Calling generate_bgm with a path that was never rendered, was already deleted by a cleanup step, lives on an unmounted volume, or points at a directory.

Common situations: Race between a temp-file cleanup and the BGM step in the pipeline, passing a relative path while the process cwd changed, video rendered in a container path not mounted into the worker, or a typo'd path from task config.
