I found a similar solved discussion that might help you troubleshoot your issue: Troubleshoot LangSmith logging issues ^[1].

In your case, it seems like the environment variable for the API key might not be set correctly. Here is the correct way to set the environment variables in your Python script:

import getpass
import os

os.environ["LANGCHAIN_TRACING_V2"] = "true"
os.environ["LANGSMITH_ENDPOINT"] = "https://api.smith.langchain.com"
os.environ["LANGCHAIN_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")
os.environ["LANGCHAIN_PROJECT"] = "My_project"

Make sure you are using getpass.getpass to securely input your API key. This should resolve the LangSmithMissingAPIKeyWarning error ^[2].

Additionally, ensure that you are using the correct version of langsmith as required by langchain. According to the documentation, langchain requires langsmith version ^0.1.17 ^[3]. You might want to check your langsmith version and update it if necessary.
