Unable to upload files in Q&A Chatbot's RAG service

[Minxiangliu]

Hi there,
I'm currently trying to build a Q&A Chatbot using the example here. Since my GPU model is A30 (with two 20GB GPUs), I'm using a smaller-scale model: llama-2-7B-chat. I followed the instructions in the example to set up the service, but I'm having trouble uploading knowledge documents. What can I do here to solve the problem?
