The workflow file does not exist: {workflow_path}

Error message

The workflow file does not exist: {workflow_path}

What it means

generate_audio_visual_video in web/pipelines/action_transfer.py resolves the ComfyUI workflow as Path('workflows') / workflow_key and raises a plain Exception if that file does not exist on disk before loading its JSON config.

Solutions

1. Verify the file workflows/<workflow_key> exists relative to the app's working directory (ls workflows/)
2. Download or restore the missing workflow JSON into the workflows directory
3. Fix the workflow_key value in the pipeline settings to match an existing file name
4. Launch the app from the repository root so the relative 'workflows' path resolves

Example fix

// before
workflow_key = "audio_visual_custom.json"  # file doesn't exist
// after
workflow_key = "action_transfer.json"  # exists under workflows/

from pathlib import Path
workflow_path = Path("workflows") / workflow_key
if not workflow_path.is_file():
    raise FileNotFoundError(f"Workflow missing: {workflow_path.resolve()}")

try:
    video_url = await generate_audio_visual_video(...)
except Exception as e:
    if "workflow file does not exist" in str(e):
        st.error(f"Workflow '{workflow_key}' not found under workflows/; restore it or pick another.")

When it happens

Trigger: _render_output_preview renders the action-transfer pipeline with a workflow_key whose file is missing under the 'workflows' directory relative to the current working directory — e.g. a renamed, deleted, or never-downloaded workflow JSON, or the app was launched from a different working directory.

Common situations: Fresh checkout without the workflows folder populated; user configured a custom workflow key that doesn't match a file name; running the web app from a directory other than the repo root so the relative 'workflows' path doesn't resolve.
