1 month ago Hello @pratham-jaiswal 👋, I'm Dosu, here to help you with any bugs, questions, or contributions.
The error you're encountering, Uncaught SyntaxError: Invalid left-hand side in assignment, typically occurs when there is an issue with the way the code is being bundled or transpiled. This can sometimes happen due to version conflicts or misconfigurations in your build tools like Webpack or Babel.
Here are a few steps to troubleshoot and resolve this issue:
-
Check Dependencies and Peer Dependencies: Ensure that the versions of
@langchain/cohereand@langchain/coreare compatible. According to the@langchain/coherepackage, it requires@langchain/coreversion>=0.2.21 <0.4.0[1]. -
Update
package.json: Make sure yourpackage.jsonenforces the same version of@langchain/coreacross all LangChain packages. You can do this by addingresolutionsandoverridesfields:{ "name": "something", "version": "0.1.0", "private": true, "dependencies": { "@langchain/cohere": "^0.3.0", "@langchain/core": "^0.3.3", "@testing-library/jest-dom": "^5.17.0", "@testing-library/react": "^13.4.0", "@testing-library/user-event": "^13.5.0", "react": "^18.3.1", "react-dom": "^18.3.1", "react-scripts": "5.0.1", "web-vitals": "^2.1.4" }, "resolutions": { "@langchain/core": "0.3.3" }, "overrides": { "@langchain/core": "0.3.3" }, "pnpm": { "overrides": { "@langchain/core": "0.3.3" } }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" }, "eslintConfig": { "extends": [ "react-app", "react-app/jest" ] }, "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] } } -
Clear Cache and Reinstall Dependencies: Sometimes, clearing the cache and reinstalling dependencies can resolve bundling issues.
rm -rf node_modules rm -rf yarn.lock package-lock.json yarn cache clean yarn install -
Check Webpack Configuration: Ensure that your Webpack configuration is correctly set up to handle ES modules. You might need to adjust the
modulerules to include the@langchainpackages. -
Babel Configuration: If you are using Babel, ensure that it is configured to transpile the
@langchainpackages correctly. You might need to include these packages in theincludeorexcludeoptions of your Babel loader. -
Example Code: Here is a minimal example of how to use
ChatCoherein a React application:import React from "react"; import { ChatCohere } from "@langchain/cohere"; const App = () => { const llm = new ChatCohere({ model: "command-r-plus", temperature: 0, maxRetries: 2, }); return ( <div> <h1>hi</h1> </div> ); }; export default App;
By following these steps, you should be able to resolve the issue and successfully import and use ChatCohere in your React application.

Error Message and Stack Trace (if applicable)
The only error I'm getting is the following
Which is coming from
import { ChatCohere } from "@langchain/cohere";bundle.js:23926:5 :
Description
I am trying to use the
ChatCohereintegration in a React project by importing it from the@langchain/coherepackage. I expect the import to work correctly, allowing me to interact with the Cohere LLM in my application. However, upon importing, I am encountering a runtime aforementioned error, which prevents the application from functioning as expected. This error points to thebundle.jsfile and only occurs when I importChatCohere.System Info
