## Summary `reindex_embeddings` crashed with `ModuleNotFoundError: No module named 'networkx'` when Unstructured hit spreadsheet files via `partition/xlsx.py`. Reindex clears Chroma first, so a mid-run crash leaves an empty/partial vector store. ### True fix Depend on **`unstructured[xlsx]==0.18.21`** (not bare `unstructured`). That extra pulls the required spreadsheet partition deps: `networkx`, `msoffcrypto-tool`, `xlrd` (plus openpyxl/pandas already present). ### Resilience Also catch per-document ingest failures so one corrupt/unsupported file cannot abort a full rebuild after Chroma was cleared. Successful files still ingest; failures are logged. ## Test plan - [x] CI / unit tests on this PR - [ ] Merge + redeploy image to all hosts - [ ] On each host: `docker compose -p chat_backend_prod exec web bash -lc 'cd /app/llm_be && SKIP_RAG_INIT=1 uv run python manage.py reindex_embeddings'` - [ ] Confirm non-zero chunk count and no `networkx` / `msoffcrypto` / `xlrd` import errors ## Ops workaround (running containers only, until deploy) ```bash uv pip install 'unstructured[xlsx]==0.18.21' cd /app/llm_be && SKIP_RAG_INIT=1 uv run python manage.py reindex_embeddings ```Reviewed-on: #66
