getPromptStateless received 403 error when using LangfuseWeb SDK

[huangbaitu123]

import { LangfuseWeb } from "langfuse"

const langfuseweb = new LangfuseWeb({
  publicKey: process.env.LANGFUSE_PUBLIC_KEY,
  baseUrl: process.env.LANGFUSE_BASEURL,
})

langfuseweb.getPromptStateless("ai-tools-dev-test").then((res) => {
  res.data === {
    message: 'Access denied - need to use basic auth with secret key to GET prompts',
    error: 'ForbiddenError'        
  }
}
})

LangfuseWeb do not accept secretKey, but getPromptStateless needs basic auth, so this is paradox?

Thanks for the feedback, getPromptStateless is an internal method which is not documented. You need to use import { Langfuse } from "langfuse" and authenticate with secret and public key to use getPrompt(). See this documentation section for more details: https://langfuse.com/docs/prompts/get-started#use-prompt

I'll create an issue as this is confusing and could be improved, thanks again for the feedback!
