When does this happen?

IF TypeError: memoryview: a bytes-like object is required, not 'Document' when using ParentDocumentRetriever with LocalFileStore or RedisStore

How others solved it

THEN Serialize Document objects into bytes using pickle.dumps before storing them in the docstore (e.g., LocalFileStore.mset). Modify the add_documents method to produce serialized key-value pairs: [(id, pickle.dumps(doc)) for id, doc in full_docs]. When retrieving, deserialize with pickle.loads.

import pickle

def add_documents(self, documents, ids, add_to_docstore=True):
    ...
    if add_to_docstore:
        serialized_docs = [(id, pickle.dumps(doc)) for id, doc in full_docs]
        self.docstore.mset(serialized_docs)
