File {data_path} not found.
Error message
File {data_path} not found. What it means
IndexableDocument.from_path first verifies the data file exists; a missing data_path raises FileNotFoundError echoing the path. This is the entry guard for the RAG indexing pipeline before read_data() attempts format-specific loading.

Solutions
- Resolve to an absolute path and assert existence before indexing.
- Verify mounts/volumes and cwd in containerized runs.
- Create or re-download the data file at the expected location.
Example fix
# before
doc = IndexableDocument.from_path(Path('data/faq.csv')) # FileNotFoundError
# after
p = Path('data/faq.csv').resolve()
assert p.is_file(), f'data file missing: {p}'
doc = IndexableDocument.from_path(p) Defensive patterns
Strategy: validation
Validate before calling
p = data_path.resolve()
if not p.is_file():
raise FileNotFoundError(f'data file missing: {p}')
doc = IndexableDocument.from_path(p, content_col=content_col) Type guard
def is_existing_file(p: Path) -> TypeGuard[Path]:
return p.exists() and p.is_file() Prevention
- Verify data volumes/mounts in containerized runs.
- Use absolute paths for data files in indexing scripts.
- Add a preflight existence check over the full file list before batch indexing.
When it happens
Trigger: IndexableDocument.from_path(Path('knowledge/base.xlsx')) where the directory or file does not exist; relative paths resolved from a different cwd; typo in the filename; mount/volume not attached in containers.
Common situations: Docker deployments where the data volume is not mounted at the expected path; notebooks run from a different working directory; data files moved or renamed after the indexing script was written.
