The community member is experiencing an error when evaluating RAG using LlamaDataset from LlamaHub, specifically an "Illegal header value b'Bearer '" and an "APIConnectionError". The comments suggest that this is likely due to the API key not being set correctly, particularly the OpenAI key. One community member notes that the key works fine for fetching activities, while another suggests ensuring the right ServiceContext class is used and that the set_global_service_context function can be helpful. There is no explicitly marked answer in the comments.
