Known Issues

• https://github.com/langchain4j/langchain4j/issues/1948 Pinecone stores all numbers as floating-point values, which means Integer and Long values (e.g., 1746714878034235396) stored in Metadata may be corrupted and returned as incorrect numbers! Possible workaround: convert integer/double values to String before storing them in Metadata. Please note that in this case metadata filtering might not work properly!
