Hello @gognjanovski! I'm here to help you with your LangChain.js issue. I'm a bot designed to assist with bug fixes, questions, and contributions. Let's work together to resolve the issue you're experiencing.

I found some relevant information that might help with the issue you're facing.

1. Similar Issues and Discussions:

   • There is a similar discussion about an import error related to package subpaths: [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './dist/document_loaders/web/cheerio' is not defined by "exports" in \node_modules\@langchain\community\package.json ^[1].
   • Another discussion about unit test errors with Jest might provide some insights: Error while running unit tests with Jest ^[2].
   • A related issue with Vite build errors: Vite v5 react cannot build: Error: [commonjs--resolver] Failed to resolve entry for package "@langchain/core" ^[3].

2. Possible Cause and Solution:

   • The error "ParsedChatCompletion not found in 'openai/resources/beta/chat/completions.mjs'" occurs because the ParsedChatCompletion is being imported from a module that does not exist or is not correctly referenced in your project. Verify the correct path and export for ParsedChatCompletion in the openai package or remove the import if it is not needed ^[4].
   • Ensure that ParsedChatCompletion is a valid export in the openai/resources/beta/chat/completions.mjs file. According to the LangChain.js repository, it is a valid export ^[4].

3. Dependencies:

   • Check the dependencies and peer dependencies in your package.json file. The relevant dependencies are:

     "openai": "^4.41.1"

     and peer dependencies:

     "@langchain/openai": ">=0.1.0 <0.3.0"

     Ensure these are correctly installed and compatible with your project ^[5].

4. Alternative Methods:

   • The LangChain.js documentation provides alternative modules or methods for achieving similar functionality as ParsedChatCompletion. You can use Runnable, RunnablePassthrough, and RunnableSequence for structured output methods. Here is an example:

     withStructuredOutput<RunOutput extends Record<string, any> = Record<string, any>>(
     outputSchema: StructuredOutputMethodParams<RunOutput, boolean> | z.ZodType<RunOutput> | Record<string, any>,
     config?: StructuredOutputMethodOptions<boolean>
     ): Runnable<BaseLanguageModelInput, RunOutput> | Runnable<BaseLanguageModelInput, { raw: BaseMessage; parsed: RunOutput }> {
     // Implementation details...
     }

     This code snippet demonstrates how to use structured output methods with Runnable, RunnablePassthrough, and RunnableSequence to achieve similar functionality ^[6][4].

By following these steps, you should be able to resolve the import error and continue building your Node.js project with the LangChain package.
