Error Processing Query: Pydantic Validation Error for TextNode

Hello LLama PPL , i am facing an annoying error:

Plain Text

ERROR:root:Error processing query: 1 validation error for TextNode
text
  Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]
    For further information visit https://errors.pydantic.dev/2.10/v/string_type

i could not know how even to debug it right: i am using this :

Plain Text

def query_vector_store(self, query: str, top_k: int = 15):
        retriever = VectorStoreIndex.from_vector_store(self.vector_store).as_query_engine(llm=self.get_llm, similarity_top_k=top_k)
        response = retriever.query(query)
        return response

to query a vector store that is in Supabase collection is already exist, i am using this method through fastapi endpoint

i am getting `error: TypeError:

i am getting error: TypeError: FunctionTool.from_defaults() missing 1 required positional argument: 'fn'
my methods are Async functions so they need to be await

pick_func = FunctionTool.from_defaults(async_fn=flight_service.create_pickup_flight_alert)
any idea why the error is up?

@Logan M do you think it's time to bump

@Logan M do you think it's time to bump Pydantic up and start rid off the Deprecations messages from pydantic?
example:The schema method is deprecated; use model_json_schema instead. Deprecated in Pydantic V2.0 to be removed in V3.0.

i didn't understand this "The output is a valid Pydantic object that we can then use to call functions/APIs" in:
https://docs.llamaindex.ai/en/stable/examples/output_parsing/openai_pydantic_program/

i already returning the valid pydantic model from OpenAIPydanticProgram.from_defaults but i get lost where to use it, i wanna feed the generated dict to another agent so it can call a functions.

devs i need some suggestions in my use

devs i need some suggestions in my use case here:
i saving docs that have users info in Supabase bucket, i need to load it to be used by llm agent to extract the needed data , like in the example here : https://docs.llamaindex.ai/en/stable/examples/usecases/email_data_extraction/
so i need the best practice, do i need to just create temp dir and download it? or convert the needed data to Vectors and save it then retrieve it by llm.
i am a bit Lost tbh. 😟

ok i am having issue using openai assistant using llamaindex: i got this error:

ImportError: cannot import name 'MessageContentText' from 'openai.types.beta.threads' (/llm-test/pythonProject/.venv/lib/python3.12/site-packages/openai/types/beta/threads/__init__.py). Did you mean: 'MessageContentDelta'?

I think we need to open issue and change or update the import then open PR
