langchain-chat-with-documents: Error while uploading files "Failed to index document"

I have all the packages up to date, review my Weaviate, cloudflare and OpenAI API. Everything seems to be correct.

I see in cloudflare that the files are correctly uploaded.

This is the error in console when uploading a .txt simple file: `- ready started server on 0.0.0.0:3000, url: http://localhost:3000
