> QdrantEmbeddingsDataTypeTransformer (around lines 56-58) maps document metadata into the Qdrant point payload with:
>     metadata.toMap().forEach((k, v) -> builder.putPayload(k, ValueFactory.value((String) v)));
> The unchecked (String) v cast throws ClassCastException as soon as a metadata value is not a String. This happens routinely in practice because langchain4j document splitters populate numeric metadata such as the chunk index and page number, so a normal ingestion pipeline that stores metadata will fail at runtime.
> The pgvector sibling transformer handles Number/Boolean values in addition to String. Fix: branch on the value type (String / Number / Boolean) and build the matching Qdrant Value via ValueFactory, or fall back to String.valueOf(v) for unknown types.
