Did not find openai_api_key, please add an environment variable OPENAI_API_KEY which contains it, or pass openai_api_key as a named parameter. (type=value_error)

I get the same error when I try to run this, This used to work and I've tried updating my openai api key but still get errors.

export OPENAI_API_KEY="sk-foo"
