The error "TypeError: Cannot read properties of undefined (reading 'text')" typically occurs when the code is trying to access the 'text' property of an object that is undefined
. This suggests that the documents being passed to Pinecone are not in the expected format.
Steps to Resolve the Issue
-
Verify Document Structure:
Ensure that each document has atext
property before passing it to Pinecone. Add the following logging to youringest-data.ts
script to inspect the structure of the documents after they are split:const docs = await textSplitter.splitDocuments(rawDocs); console.log('split docs', docs); // Check if all documents have the 'text' property docs.forEach((doc, index) => { if (!doc.text) { console.error(`Document at index ${index} is missing the 'text' property`, doc); } });
-
Ensure Correct Pinecone Configuration:
Make sure your.env
file is correctly set up with the necessary Pinecone configuration. Ensure your.env
file includes thePINECONE_INDEX_NAME
variable:PINECONE_INDEX_NAME=pdf
-
Check CustomPDFLoader Implementation:
TheCustomPDFLoader
class should ensure that each document has atext
property. Verify that thepageContent
property of theDocument
object is set toparsed.text
, which should contain the text content of the PDF.export class CustomPDFLoader extends BufferLoader { public async parse( raw: Buffer, metadata: Document['metadata'], ): Promise<Document[]> { const { pdf } = await PDFLoaderImports(); const parsed = await pdf(raw); return [ new Document({ pageContent: parsed.text, metadata: { ...metadata, pdf_numpages: parsed.numpages, }, }), ]; } }
-
Debugging Pinecone Ingestion:
Add more detailed logging around the Pinecone ingestion process to identify any issues:try { const docs = await textSplitter.splitDocuments(rawDocs); console.log('split docs', docs); // Check if all documents have the 'text' property docs.forEach((doc, index) => { if (!doc.text) { console.error(`Document at index ${index} is missing the 'text' property`, doc); } }); // Ingest documents into Pinecone await PineconeStore.fromDocuments(docs, { pineconeIndexName: PINECONE_INDEX_NAME, textKey: 'text', }); console.log('Successfully ingested documents into Pinecone'); } catch (error) { console.error('Failed to ingest documents into Pinecone:', error); throw new Error('Failed to ingest your data'); }
By following these steps, you should be able to identify and resolve the issue causing the "TypeError: Cannot read properties of undefined (reading 'text')" error.

The error "TypeError: Cannot read properties of undefined (reading 'text')" usually occurs when the documents being processed do not have the expected text
property. Hereโs how you can troubleshoot and fix this issue:
Steps to Troubleshoot
-
Check Document Structure: Ensure that the documents loaded by
directoryLoader.load()
have thetext
property. -
Verify Split Documents: Ensure that the documents returned by
textSplitter.splitDocuments(rawDocs)
have thetext
property. -
Add Logging: Modify your code to log the structure of the documents at each step to inspect them.
Hereโs the modified code with additional logging:
import { RecursiveCharacterTextSplitter } from 'langchain/text_splitter';
import { OpenAIEmbeddings } from 'langchain/embeddings/openai';
import { PineconeStore } from 'langchain/vectorstores/pinecone';
import { pinecone } from '@/utils/pinecone-client';
import { PDFLoader } from 'langchain/document_loaders/fs/pdf';
import { PINECONE_INDEX_NAME, PINECONE_NAME_SPACE } from '@/config/pinecone';
import { DirectoryLoader } from 'langchain/document_loaders/fs/directory';
const filePath = 'docs';
export const run = async () => {
try {
const directoryLoader = new DirectoryLoader(filePath, {
'.pdf': (path) => new PDFLoader(path),
});
const rawDocs = await directoryLoader.load();
console.log('rawDocs', rawDocs); // Log rawDocs to inspect structure
const textSplitter = new RecursiveCharacterTextSplitter({
chunkSize: 1000,
chunkOverlap: 200,
});
const docs = await textSplitter.splitDocuments(rawDocs);
console.log('split docs', docs); // Log split docs to inspect structure
console.log('creating vector store...');
const embeddings = new OpenAIEmbeddings();
const index = pinecone.Index(PINECONE_INDEX_NAME);
await PineconeStore.fromDocuments(docs, embeddings, {
pineconeIndex: index,
namespace: PINECONE_NAME_SPACE,
textKey: 'text',
});
} catch (error) {
console.log('error', error);
throw new Error('Failed to ingest your data');
}
};
(async () => {
await run();
console.log('ingestion complete');
})();
Additional Checks
- Environment Variables: Ensure your
.env
file is correctly configured with the necessary API keys and index names:
OPENAI_API_KEY=
PINECONE_API_KEY=
PINECONE_ENVIRONMENT=
PINECONE_INDEX_NAME=
- Pinecone Index Configuration: Verify that
PINECONE_INDEX_NAME
,PINECONE_ENVIRONMENT
, andPINECONE_API_KEY
are correctly set.
By following these steps, you should be able to identify and resolve the issue. If you continue to encounter problems, please provide the output of the logged structures for further assistance.

You should place the provided code in the scripts/ingest-data.ts
file. This file is responsible for ingesting data into Pinecone. Here is the complete code for scripts/ingest-data.ts
with the added logging for inspection:
import { RecursiveCharacterTextSplitter } from 'langchain/text_splitter';
import { OpenAIEmbeddings } from 'langchain/embeddings/openai';
import { PineconeStore } from 'langchain/vectorstores/pinecone';
import { pinecone } from '@/utils/pinecone-client';
import { PDFLoader } from 'langchain/document_loaders/fs/pdf';
import { PINECONE_INDEX_NAME, PINECONE_NAME_SPACE } from '@/config/pinecone';
import { DirectoryLoader } from 'langchain/document_loaders/fs/directory';
const filePath = 'docs';
export const run = async () => {
try {
const directoryLoader = new DirectoryLoader(filePath, {
'.pdf': (path) => new PDFLoader(path),
});
const rawDocs = await directoryLoader.load();
console.log('rawDocs', rawDocs); // Log rawDocs to inspect structure
const textSplitter = new RecursiveCharacterTextSplitter({
chunkSize: 1000,
chunkOverlap: 200,
});
const docs = await textSplitter.splitDocuments(rawDocs);
console.log('split docs', docs); // Log split docs to inspect structure
console.log('creating vector store...');
const embeddings = new OpenAIEmbeddings();
const index = pinecone.Index(PINECONE_INDEX_NAME);
await PineconeStore.fromDocuments(docs, embeddings, {
pineconeIndex: index,
namespace: PINECONE_NAME_SPACE,
textKey: 'text',
});
} catch (error) {
console.log('error', error);
throw new Error('Failed to ingest your data');
}
};
(async () => {
await run();
console.log('ingestion complete');
})();
Explanation of the Code
- DirectoryLoader: Loads all PDF files from the specified directory (
docs
). - Logging
rawDocs
: Logs the raw documents loaded from the directory to inspect their structure. - RecursiveCharacterTextSplitter: Splits the documents into smaller chunks.
- Logging
docs
: Logs the split documents to inspect their structure. - Creating Vector Store: Creates a vector store using the Pinecone index and the embeddings generated from the documents.
Running the Script
To run this script, use the following command in your terminal:
node scripts/ingest-data.ts
Ensure you have all the necessary environment variables set up in your .env
file, especially PINECONE_INDEX_NAME
and PINECONE_API_KEY
.
Troubleshooting
If you encounter the error TypeError: Cannot read properties of undefined (reading 'text')
, it indicates that the text
property is missing in the documents being processed. Ensure that the documents have the correct structure after being split by the RecursiveCharacterTextSplitter
. The expected structure of the docs
object is:
[
{
"text": "chunk of text",
"metadata": {
"source": "source file path or identifier"
}
},
...
]
If the structure is correct and the error persists, double-check the configuration of the Pinecone index and ensure that the textKey
property matches the key used in your documents.

Apologies for being so dumb, but which part of the program should I use this code in?

i have tried it but still not working. I get the following error. my pdf is simplest document of few pages which I converted from word to PDF so it is text property. looks like OpenAI works fine but Pinecone is not. any help is greatly appreciated.
