I want to create Q & A Chatbot using data from Vector Store Retriever with ability to calling functions.
I can do it separately but have no Idea how to put them together. any help/idea will be appreciated. 🙏

Use the ChainTool as a wrapper for your QA chain, connect it to the Function Agent on the Allowed Tools line

We have a new conversational retrieval agent coming up in next release that allow you to use Vector Store Retriever as Tool to OpenAI Agent for function calling

hello , can the chain tools show the source document of QA Chain ?

I got the data in the document and a "output values have 2 keys, you must specify an output key or pass only 1 key as output" warning .
