Hi @Sameer_Kalkeri,
Welcome to the community!
This issue looks similar to a previous discussion.
known regression since n8n 1.98 when pdfjs-dist was upgraded to a version that needs browser APIs like DOMMatrix — multiple github issues open on it (#16593, #16438, #16422).
Workaround: Bypass Document Loader for PDFs and use a Code node with the pdf-parse npm package instead. set NODE_FUNCTION_ALLOW_EXTERNAL=pdf-parse in ur env vars, extract the text in Code node, pass the extracted text into Vector Store Insert directly.
It would be great if you can share your workflow JSON to confirm if you are hitting the same issue.
Welcome to the n8n community @Sameer_Kalkeri
Update your instance to v 2.23, confirm that your Node.js version is the latest, and if nothing works, consider using a dedicated node for extracting text from PDFs (like PDF to Text) or a code node using libraries like pdf-parse or pdfjs-dist, which don’t depend on browser APIs to function.
i am a beginner, could you please guide me step by step…these terms are too technical

if you can, please share your json without sensitive data so we can better understand your case.
Hi @Sameer_Kalkeri Welcome!
Try this flow:
i tried this flow …why there is no output now?
This is strange, as there is no error, but the node ran successfully. Have you checked the Pinecone store?
