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"

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 happens because your LangSmith API key is missing, invalid, or expired. Here is how you can fix it:
1. Generate a new API key:
Go to Smith LangChain $\rightarrow$ Settings $\rightarrow$ API Keys $\rightarrow$ Create API Key.

2. Set up your environment variables:

# Set your valid API key
export LANGCHAIN_API_KEY="ls__your_key_here"

# Enable tracing
export LANGCHAIN_TRACING_V2="true"

Or, if you don't need LangSmith tracing at all, disable it in your Python script:

import os

# Disable LangSmith tracing to bypass the API call entirely
os.environ["LANGCHAIN_TRACING_V2"] = "false" 

To wrap things up, that 403 Forbidden error just means your LangSmith API key isn't set up or has expired.
You can easily fix it by generating a new key from your Smith LangChain dashboard and
adding it as an environment variable, or by turning tracing off completely if you don't need it.
Hope this helps you get past the block and running smoothly!
