Related Issues

• fixes Chroma - The meta in write_documents only supports str, int, float, bool, but not list. However, its search filter does support list. #2214

Proposed Changes:

Update validation logic to support lists of supported ChromaDB metadatas types.

How did you test it?

Modified existing tests. I also ran the following script to test that the issue the user mentioned has been fixed:

from haystack import Document

from haystack_integrations.document_stores.chroma import ChromaDocumentStore

doc = Document(content="test", meta={"countries": ["UK", "US"]})

document_store = ChromaDocumentStore()
number = document_store.write_documents([doc])
print(number)
