The second step workflow file does not exist:{second_workflo

Error message

The second step workflow file does not exist:{second_workflow_path}

What it means

generate_digital_human_video in web/pipelines/digital_human.py loads a two-stage pipeline; at the concatenation stage it resolves Path from video_params['second_workflow_path'] and raises if the file does not exist before reading its JSON.

Solutions

1. Check that second_workflow_path in the settings points to an existing file and correct it
2. Use an absolute path for second_workflow_path to avoid working-directory issues
3. Restore or re-download the missing second-step workflow JSON
4. Verify file permissions allow the app process to read the path

Example fix

// before
"second_workflow_path": "workflows/dh_step2_old.json"  # missing
// after
"second_workflow_path": "/abs/path/workflows/dh_step2.json"  # exists

from pathlib import Path
p = Path(video_params["second_workflow_path"])
if not p.is_file():
    raise FileNotFoundError(f"Second-step workflow missing: {p.resolve()}")

try:
    await generate_digital_human_video(...)
except Exception as e:
    if "second step workflow file does not exist" in str(e):
        st.error(f"Second workflow not found: {e}; fix second_workflow_path in settings.")

When it happens

Trigger: The two-step digital human flow reaches ~65% progress, then Path(second_workflow_path).exists() is False — the second workflow JSON path is misconfigured, the file was moved/deleted, or a relative path no longer resolves from the current working directory.

Common situations: Settings pointing at a workflow file that was renamed; migrating machines without copying the second workflow; using a relative path while launching the app from another directory.
