langchainjs

Hm.... Thanks for flagging. Taking a look now. Edit: Ok. I haven't been able to reproduce this issue (I know "it worked on my machine" is the worst answer. But I did do a fresh setup on two other machines to see if I can recreate so it worked on three of my machines?). If you want to drop me an email (my email is in my profile), I'm happy to help find time to debug live and I'd personally love to find out what the issue is. And/or hook you up with a t-shirt :) Digging in, this specific error looks like it is happening when LangChain is trying to strip out new lines (you can see the code in LangChain here: https://github.com/hwchase17/langchainjs/blob/main/langchain...). For some reason your documents or embeddings are undefined. But I've been unable to create a scenario where that happens. I wondered if perhaps your OpenAI API Key wasn't

There are two Javascript alternatives, but how robust the development is remains to be seen: https://github.com/hwchase17/langchainjs https://github.com/cfortuner/promptable

This is just an example [0] if you want to use embeddings with ChatGPT using langchainJS [1] and chromadb [2]. There weren't many examples so figured I would share this incase it helps someone out. You can also switch from chromadb to whatever (hnswlib for example is dead simple and you can save embeddings to disk). I put a telegram bot as an example. Be "responsible" :P and have fun!
