Hello @langsmith. The error in your screenshot is a 403 Forbidden from LangSmith's API:

Failed to POST https://api.smith.langchain.com/runs/multipart
HTTPError('403 Client Error: Forbidden')

This means your LangSmith API key is missing, wrong, or expired. Here's what to do:

1. Get a fresh API key → go to https://smith.langchain.com → Settings → API Keys → Create API Key

2. Set these environment variables:

export LANGCHAIN_API_KEY="ls__your_key_here"
export LANGCHAIN_TRACING_V2="true"

Or if you don't need LangSmith tracing at all, just disable it:

export LANGCHAIN_TRACING_V2="false"

or in Python before your code runs:

import os
os.environ["LANGCHAIN_TRACING_V2"] = "false"
