ValidationError: 1 validation error for NodeWithScore node Can't instantiate abstract class BaseNode with abstract methods get_content, get_metadata_str, get_type, hash, set_content (type=type_error

with this code :

vector_store = PineconeVectorStore(pc.Index(data.index),namespace=data.name)
index = VectorStoreIndex.from_vector_store(vector_store=vector_store,service_context=serviceContext)

retriever = index.as_retriever(similarity_top_k=int(data.nbrTop),filters=filters)
retriever.retrieve("test") #HERE
print(data)
