Langsmith expose is not working Azure OpenAI services

[mrcmoresi]

Issue you'd like to raise.

Hi everyone, I'm trying to deploy and use langsmith locally.
I deployed in a docker container using

langsmith start --expose --openai-api-key=<my azure OpenAi key>

the docker container looks good

I opened all the used ports to avoid any problem there, I'm running langsmith in a remote computer

I set up the environment variables
LANGCHAIN_TRACING_V2=true
LANGCHAIN_ENDPOINT=https://cc23-20-79-217-xxx.ngrok.io
LANGCHAIN_API_KEY=

but the interface is not loading the projects

when I try to access the langsmith endpoint it returns

{
"detail": "Not Found"
}

using the chat example that appears in this repo
https://github.com/langchain-ai/langsmith-cookbook/tree/main/feedback-examples/streamlit

I can see in the endpoint https://cc23-20-79-217-xxx.ngrok.io that the runs are being tracked, but I can't see them in the frontend

debugging the front end it is failing trying to fetch the tenants, it's trying to fetch them from http://127.0.0.1:1984/tenants while if I'm not understanding it wrong it should get them from http://20.79.217.xxx:1984/tenants

could it be a problem with the Azure OpenAI? or did I do something wrong with the installation?

Thanks in advance

Hi there,

Thanks for reaching out and providing detailed information about your issue. Based on the information you've provided, it seems like the issue might not be directly related to Azure OpenAI, but rather to the setup of your environment variables or the LangSmith platform itself.

Firstly, ensure that you have correctly set up the environment variables LANGCHAIN_TRACING_V2, LANGCHAIN_PROJECT, LANGCHAIN_ENDPOINT, and LANGCHAIN_API_KEY. The LANGCHAIN_TRACING_V2 should be set to "true", LANGCHAIN_PROJECT should be the name of your project, LANGCHAIN_ENDPOINT should be "https://api.smith.langchain.com", and LANGCHAIN_API_KEY should be your API key.

Here's an example of how you can set these variables in Python:

import os
from uuid import uuid4

unique_id = uuid4().hex[0:8]
os.environ["LANGCHAIN_TRACING_V2"] = "true"
os.environ["LANGCHAIN_PROJECT"] = f"Tracing Walkthrough - {unique_id}"
os.environ["LANGCHAIN_ENDPOINT"] = "https://api.smith.langchain.com"
os.environ["LANGCHAIN_API_KEY"] = ""  # Update to your API key

Secondly, make sure you have created a LangSmith account and generated an API key. You can do this at https://smith.langchain.com/.

Lastly, check if the LangSmith platform is currently operational. As mentioned in the guide, LangSmith is in closed beta and they are in the process of rolling it out to more users.

If you have checked all these and the issue persists, it might be a good idea to reach out to LangSmith support at support@langchain.dev for further assistance.

Regarding the "Not Found" error, a common mistake that could lead to this error is if the BACKEND_URL for the frontend service is not correctly set to the URL of the backend service. In this case, the frontend service would not be able to communicate with the backend service, leading to a "Not Found" error. Another possible issue could be if the PORT for the backend service is not correctly exposed or if the LANGCHAIN_ENV is not correctly set.

I hope this helps! Let me know if you have any other questions or if there's anything else I can assist you with.

Best,
Dosu

Hi @mrcmoresi , I am facing the same issue while trying to host the application in a GCP VM. Were you able to fix this?

Hi @sudevschiz unfortunately I couldn't spend more time on it. in the following weeks I'll try to find a solution to this problem.

Hi, @mrcmoresi,

I'm helping the LangChain team manage their backlog and am marking this issue as stale. From what I understand, you reported an issue with the Langsmith expose feature not working with Azure OpenAI services. You deployed Langsmith in a Docker container, set up the necessary environment variables, but the interface is not loading the projects. The frontend is failing to fetch tenants from the correct endpoint, and you suspect it may be a problem with Azure OpenAI or the installation process. Detailed troubleshooting steps were provided, and another user mentioned facing a similar issue while hosting the application in a GCP VM. You acknowledged the issue and expressed intent to spend more time finding a solution in the following weeks.

Could you please confirm if this issue is still relevant to the latest version of the LangChain repository? If it is, please let the LangChain team know by commenting on the issue. Otherwise, feel free to close the issue yourself, or the issue will be automatically closed in 7 days. Thank you!
