FileNotFoundError

Error message

FileNotFoundError: {path}

What it means

For every path listed in config['evidence_files'], run_workflow resolves it via resolve_input and requires it to be an existing regular file (path.is_file()). If the resolved path does not exist or is a directory/symlink-to-nothing, FileNotFoundError is raised with the path. Evidence files are hashed and probed, so they must be readable files.

Solutions

1. Check the file exists at the exact resolved path: ls the path from config['evidence_files']
2. Confirm the working directory / resolve_input base path matches where evidence files actually live
3. Correct typos in the evidence path in the workflow config
4. Replace directory entries with the actual file paths inside that directory

Example fix

// before
evidence_files = ['out/collateral/report']
// after
evidence_files = ['out/collateral/report.pdf']

from pathlib import Path
for raw in config.get('evidence_files', []):
    p = Path(raw)
    if not p.is_file():
        raise FileNotFoundError(f'evidence file missing: {p.resolve()}')

def evidence_files_exist(config) -> bool:
    return all(Path(p).is_file() for p in config.get('evidence_files', []))

try:
    run_workflow(config, out_dir)
except FileNotFoundError as e:
    print(f'Evidence file not found: {e.filename}; check paths and working directory')

When it happens

Trigger: config['evidence_files'] contains a path that does not exist on disk, points to a directory, or is a broken symlink, after resolve_input processing.

Common situations: Evidence file moved or deleted after the config was written; relative path resolved against a different working directory than expected; typo in filename or extension; passing a directory instead of a file.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
