Issue: 401 Unauthorized when following langsmith tracing instructions

[sahellebusch]

Issue you'd like to raise.

Added my first project and API keys to test out the tracing functionality. Followed the instructions in the docs and set the following values:

LANGCHAIN_TRACING_V2=true
LANGCHAIN_ENDPOINT="https://api.smith.langchain.com"
LANGCHAIN_API_KEY="REDACTED"

And I keep getting the following:

Error: Failed to batch create run: 401 Unauthorized {"detail":"Invalid token"}

Everything else works. The model calls and responds correctly. Any advice here?

Suggestion:

No response

Could you confirm that if you create a new API key in the app and re-run this code it still doesn't work?

[sahellebusch]

I've already created a new API key twice now.

[hinthornw]

What is the actual code you are running?

[sahellebusch]

Omitting some details for brevity.

this.openAI = new ChatOpenAI({
      openAIApiKey: process.env.OPENAI_API_KEY,
      modelName: 'gpt-4-turbo-preview',
      temperature: 0.8,
    });

const prompt = await hub.pull<ChatPromptTemplate>(
      'seanhellebusch/[redacted]',
    );

    const res = await prompt
      .pipe(this.openAI)
      .pipe(this.outputParser)
      .invoke({ input, data: this.getDataXml() });

I have the same problem and I think the cause is we haven't added the payment yet?

[hinthornw]

No payment is required to send traces to langsmith.

@sahellebusch are you including the literal '"' quotes in your api key?

[sahellebusch]

@hinthornw - nope.

Having the same issue.

[VINHTRAN-VICIDEV]

thanks @hinthornw, it's working

[sahellebusch]

@VINHTRAN-VICIDEV - Does your issues relate to mine at all? If yes, how did you resolve?

[sahellebusch]

Welp, not sure where I copy/pasted it from but it's the "HUB" api key, needs to just be LANGCHAIN_API_KEY and it all works just fine.
