Use knowledge bank in API Designer

rafael_rosado97

Hello, Dataiku Team

I am trying to deploy an endpoint to API node where I can use knowledge bank object from my project flow.

I am using this code example but when I write this line:

vector_store = kb.as_langchain_vectorstore()

I get the next error:

Failed: 

Failed to run function : <class 'requests.exceptions.InvalidSchema'> : No connection adapters were found for '127.0.0.1:61068/dip/api/tintercom/knowledge-bank/get'

Even, I tried to use dataikuapi but the same:

import dataiku

import dataikuapi

from langchain.chains.question_answering import load_qa_chain

from dataiku.langchain.dku_llm import DKUChatLLM


def starting_chatbot(user_query):

    KB_ID = "my_kb_key" # Fill with your KB id

    GPT_LLM_ID = "my_llm_id"  # Fill with your LLM-Mesh id



    host = 'my_host'

    apiKey = 'my_key'

    client = dataikuapi.DSSClient(host, apiKey)

    project = client.get_project("PROJECT_NAME")

    kb = project.get_knowledge_bank(id=KB_ID)

    kb_core = kb.as_core_knowledge_bank()


    lc_vs = kb_core.as_langchain_retriever()

Do you know why it happens?

Thank you!
