Hi, I ran a code last week which was running fine but when I ran the same code this week it started throwing the error: Connected to pydev debugger (build 231.9011.38) Traceback (most recent call

Hi @rajaniesh Check to see if the index has been deleted. Running index.query, etc. with a non-existent index name will return the message "Failed to connect; did you specify the correct index name? > **[Quickstart](https://docs.pinecone.io/docs/quickstart#3-hello-pinecone)** > > How to get started with the Pinecone vector database. ![image](https://us1.discourse-cdn.com/flex020/uploads/pinecone/original/1X/431417d8a91e6ee103baeff11400812a5ebb78a7.png) ---

I am running the same query, and trying to delete a specific namespace in an index. Thing is, even if the namespace exists it throws this error when I run the script through a DAG on airflow. When I run the exact same code on a jupyter notebook, everything works fine. Even if I enter a non-existent namespace for the same index, code still runs, does not give an error. Any clue as to what is the case here?
