        ??? note "Troubleshooting"

            If this test fails, check that `get_by_ids` is implemented and does not
            raise an exception when given IDs that do not exist.

            !!! note
                `get_by_ids` was added to the `VectorStore` interface in
                `langchain-core` version 0.2.11. If difficult to implement, this
                test can be skipped by setting the `has_get_by_ids` property to
                `False`.

                ```python
                @property
                def has_get_by_ids(self) -> bool:
                    return False
                ```
