Bug: @langchain/mistralai - Error [ERR_REQUIRE_ESM]: require() of ES Module

gkhngyk commented 7 months ago

When I try to import ChatMistralAI I get the following error:

/Users/Desktop/xamax/server/node_modules/@langchain/mistralai/dist/chat_models.cjs:8
const mistralai_1 = __importDefault(require("@mistralai/mistralai"));
                                    ^

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/Desktop/xamax/server/node_modules/@mistralai/mistralai/src/client.js from /Users/Desktop/xamax/server/node_modules/@langchain/mistralai/dist/chat_models.cjs not supported.
Instead change the require of client.js in /Users/Desktop/xamax/server/node_modules/@langchain/mistralai/dist/chat_models.cjs to a dynamic import() which is available in all CommonJS modules.

Hello @gkhngyk! I'm Dosu, a friendly bot who's here to assist you with pesky bugs, answer your queries, or guide you on how to contribute to our repository. While we're waiting for a human maintainer to join us, I'm here to make your experience smoother! Let's get started, shall we?

The error you're encountering is due to the fact that the @langchain/mistralai package is defined as an ES module, as indicated by the "type": "module" line in its package.json file. This means that it uses the import/export syntax, which is not compatible with the require() function used in CommonJS modules.

However, the package.json file also specifies an alternative entry point for require() calls via the "require": "./index.cjs" line under "exports". This means that you should be able to import the package using require() if you're running your code in a CommonJS environment.

If you're still encountering the error, it could be due to one of the following reasons:

The index.cjs file does not exist or is not correctly exporting the ChatMistralAI object.
Your Node.js version is below 18, as specified by the "engines": { "node": ">=18" } line. Node.js 12.17.0 and later versions support ES modules, but full support, including the "exports" field in package.json, was not added until Node.js 14.

To resolve the issue, you can try the following:

Make sure you're running Node.js 18 or later.

Use the import syntax if your environment supports it:

import { ChatMistralAI } from '@langchain/mistralai';

If you're in a CommonJS environment, use require() with the specific path to the index.cjs file:
```
const { ChatMistralAI } = require('@langchain/mistralai/index.cjs');
```
Check if the index.cjs file exists and is correctly exporting the ChatMistralAI object.

You can refer to the libs/langchain-mistralai/package.json for more details.

Also, there have been similar issues reported in the past, you can refer to these for more context:

Please let me know if this helps or if you need further assistance.

hey @gkhngyk the issue should be resolved if you bump your @langchain/mistralai package to 0.0.2

whoops sorry about that, I thought they fixed that with their new sdk update... Fix is here, will be released in a few min: https://github.com/langchain-ai/langchainjs/pull/4561

Anyone else?

Can someone provides its dependencies versions about langchain? I also tried with https://github.com/langchain-ai/langchainjs/tree/main/libs/langchain-mistralai versions but same.

EDIT2: if upgrading @langchain/core I have a new error from the Mistral API ... {"object":"error","message":{"detail":[{"type":"extra_forbidden","loc":["body","tools"],"msg":"Extra inputs are not permitted","input":[],"url":"https://errors.pydantic.dev/2.5/v/extra_forbidden"}]},"type":"invalid_request_error","param":null,"code":null}. It would be great to always have a working example so people know which versions to use.
