I am creating a little chatbot using PDFs but after upserting to pinecone when we do similarity\_search then i am getting error i am doing it on vscode jupiter notebook i am providing here code and error both

from langchain.embeddings.openai import OpenAIEmbeddings  
from langchain.text\_splitter import CharacterTextSplitter  
import pinecone  
from pypdf import PdfReader  
from pinecone import Pinecone  
import os  
os.environ[“OPENAI\_API\_KEY”]=“sk-EFn2nmvPjjJCwxu96awwT3BlbkFJOC2vyUqmQD9VZpiq”  
pinecone\_env=os.environ[“PINECONE\_ENV”]=“gcp-starter”  
pinecone\_api\_key=os.environ[“PINECONE\_API\_KEY”]=“44aef121-624a-4ab5-a130-022c1f4f76”  
pdfreader=PdfReader(“test1.pdf”)  
from typing\_extensions import Concatenate  
text = “”  
for i,page in enumerate(pdfreader.pages):  
content=page.extract\_text()  
if content:  
text += content  
text\_splitter = CharacterTextSplitter(  
separator=“/n”,  
chunk\_size=1000,  
chunk\_overlap=200,  
length\_function=len  
)  
texts=text\_splitter.split\_text(text)  
embeddings = OpenAIEmbeddings()  
embed = embeddings.embed\_documents(texts)

pc = Pinecone(api\_key=pinecone\_api\_key, environment=pinecone\_env)

index = pc.Index(“test”)

if embed:  
vectorstore=index.upsert(vectors=[{“id”: “A”, “values”: embed[0]}])

else:  
print(“Embedding failed or no embeddings found.”)

from langchain.chains.question\_answering import load\_qa\_chain  
from langchain.llms import OpenAI  
chain=load\_qa\_chain(OpenAI(),chain\_type=“stuff”)  
query = “What is your name?”

embedding\_vector = OpenAIEmbeddings().embed\_query(query)  
if vectorstore is not None:  
docs = vectorstore.similarity\_search(embedding\_vector)

else:  
print(“Upsert failed or no vectors found.”)

and this is the error
