To address the "Cannot read properties of undefined (reading 'text')" error you're encountering, it's likely due to attempting to access the text property of an object that hasn't been properly initialized or is undefined. This issue is often seen when dealing with asynchronous data fetching or parsing operations that don't return the expected object structure.

1. Debug the Fetch Request: Ensure the server response is not undefined and contains the text property. Implement error handling in your fetch request to log or handle cases where the response is not as expected.

2. Verify PDF Parsing with pdf-parse: If you're using pdf-parse for PDF documents, confirm it's correctly parsing the PDF and the resulting object includes a text property. Issues here could lead to the undefined error if the expected data structure is not returned.

3. Update Dependencies: Make sure to use the latest versions of the langchain and @pinecone-database/pinecone packages. Outdated versions might contribute to compatibility issues or bugs that result in undefined objects.

4. Inspect Pinecone Index Initialization: If you're utilizing Pinecone for indexing, check that the PineconeStore.fromExistingIndex method successfully initializes with a valid index. An undefined index could prevent the proper setup of your vector store, leading to errors when accessing properties.

By following these steps, you should be able to pinpoint and resolve the issue causing the "Cannot read properties of undefined (reading 'text')" error.
