Let's Build a "Chat With PDF” app using Langchain(TS/JS), AI SDK, Pinecone DB, Open AI & Next.js 13

✨ Update ✨

Looks like Pinecone has removed namespaces from free-tier, so I pushed recent changes to https://github.com/rajeshdavidbabu/pd... and removed the name-spaces and tested the code its still working ! 🥹 🚀

Troubleshooting:
For " Error [InsufficientQuotaError]: 429 You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guid...."

I had to delete all my old API keys and created a new one + charged my credits for about 10 dollars.
