# Fix for Issue #3797 ## Problem Vector store search failed with Pydantic ValidationError when chunk metadata contained list-type values. **Error:** ``` ValidationError: 3 validation errors for VectorStoreSearchResponse attributes.tags.str: Input should be a valid string attributes.tags.float: Input should be a valid number attributes.tags.bool: Input should be a valid boolean ``` **Root Cause:** - `Chunk.metadata` accepts `dict[str, Any]` (any type allowed) - `VectorStoreSearchResponse.attributes` requires `dict[str, str | float | bool]` (primitives only) - Direct assignment at line 641 caused validation failure for non-primitive types ## Solution Added utility function to filter metadata to primitive types before creating search response. ## Impact **Fixed:** - Vector search works with list metadata (e.g., `tags: ["transformers", "gpu"]`) - Lists become searchable as comma-separated strings - No ValidationError on search responses **Preserved:** - Full metadata still available in `VectorStoreContent.metadata` - No API schema changes - Backward compatible with existing primitive metadata **Affected:** All vector store providers using `OpenAIVectorStoreMixin`: FAISS, Chroma, Qdrant, Milvus, Weaviate, PGVector, SQLite-vec ## Testing tests/unit/providers/vector_io/test_vector_utils.py::test_sanitize_metadata_for_attributes --------- Co-authored-by: Ashwin Bharambe <ashwin.bharambe@gmail.com> Co-authored-by: Francisco Arceo <arceofrancisco@gmail.com> |

Llama Stack Unit Tests
Unit Tests
Unit tests verify individual components and functions in isolation. They are fast, reliable, and don't require external services.
Prerequisites
- Python Environment: Ensure you have Python 3.12+ installed
- uv Package Manager: Install
uvif not already installed
You can run the unit tests by running:
./scripts/unit-tests.sh [PYTEST_ARGS]
Any additional arguments are passed to pytest. For example, you can specify a test directory, a specific test file, or any pytest flags (e.g., -vvv for verbosity). If no test directory is specified, it defaults to "tests/unit", e.g:
./scripts/unit-tests.sh tests/unit/registry/test_registry.py -vvv
If you'd like to run for a non-default version of Python (currently 3.12), pass PYTHON_VERSION variable as follows:
source .venv/bin/activate
PYTHON_VERSION=3.13 ./scripts/unit-tests.sh
Test Configuration
- Test Discovery: Tests are automatically discovered in the
tests/unit/directory - Async Support: Tests use
--asyncio-mode=autofor automatic async test handling - Coverage: Tests generate coverage reports in
htmlcov/directory - Python Version: Defaults to Python 3.12, but can be overridden with
PYTHON_VERSIONenvironment variable
Coverage Reports
After running tests, you can view coverage reports:
# Open HTML coverage report in browser
open htmlcov/index.html # macOS
xdg-open htmlcov/index.html # Linux
start htmlcov/index.html # Windows
