Error : Cannot get final name for export 'getRuntime' of ./node_modules/openai/_shims/auto/runtime-node.mjs

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

I am trying to use Langchain + NextJs for hosting my chatbot , and it works fine in the development server ,
But when I try to compile my code to host on the vercel server, I am getting this error

Failed to compile.

./node_modules/@langchain/openai/index.js + 66 modules
Cannot get final name for export 'getRuntime' of ./node_modules/openai/_shims/auto/runtime-node.mjs

To Reproduce

1. Make a Next Js project
2. Add openai and langchain to it
3. make a basic chain.
4. run npm run build

Code snippets

    const chain = ConversationalRetrievalQAChain.fromLLM(
      model,
      vectorStore.asRetriever()
    );
    // Format the messages
    const formattedChatPrompt = await chatPrompt.formatMessages({
      text: question,
    });

    const res = await chain.invoke({
      question,
      chat_history: formattedChatPrompt,
    });

How are you compiling your project? eg, are you using turborepo or webpack?

I'm also facing a similar kind of issue in Ubuntu

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './_shims/auto/runtime' is not defined by "exports" in /home/ubuntu/backend/node_modules/openai/package.json

Node Version - v18.12.1
Openai Version - v4.38.3

[jiveshkalra]

are you using nextjs or webapck?

I got it to work in webpack/nextjs by changing the webpack/next config

Hey @jiveshkalra how did you do that? I'm facing the same issue. I'm using next.js with monorepo.

[demenskyi]

Never mind @jiveshkalra.

For those looking for an answer try the following:

// next.config.js

/** @type {import('next').NextConfig} */
const nextConfig = {
  experimental: {
    serverComponentsExternalPackages: ["<PACKAGE_NAME>"],
  },
};

module.exports = nextConfig;

[jiveshkalra]

for me it was an issue with webpack not exporting the package files properly
I fixed it by setting this in my config

// next.config.js
/** @type {import('next').NextConfig} */
const nextConfig = { 
  webpack: (config ) => { 
    config.externals = [...config.externals, "hnswlib-node","closevector-hnswlib-node" ,"openai"]; 
    return config;
  },
};

export default nextConfig;
