fraserxu,
I followed the instructions to set up the account and tried to upload a PDF and received this error message. Have you determined the cause for the error. As far as Pinecone AI issues, it appears in the example that you provided that you were using a Free Account with an expiry date 14 days later, Mine was a 7 day free trial but it shouldn;t ake a difference unless you have tested your app while utilizing a Free Pinecone AI Starter Membership.
Regardless, any feedback would be greatly appreciated as this is a service that is very unique and it would be great to be able to utilize it!
Thank you for your efforts, they are greatly appreciated.
