The community member initially solved an issue by defining embed_model and service context, but then encountered a new problem where running pack.run resulted in a ValueError: Only one free input key is allowed. Other community members chimed in, initially thinking it was a bug, but then realizing it was not. The solution was to run pack.run(input="What did the author do growing up?"), as the readme had a typo. A community member has now submitted a pull request to fix the typo.
