Solution: Issue with `httpx` version causes `OpenAIException`

Getting Started with Rasa
1

Hi, In case anyone else runs into this; in running the tutorial on Mac Sequoia 15.1.1 (Python 3.9.21) Rasa Pro threw an exception:

APIError: OpenAIException - __init__() got an unexpected keyword argument 'proxies'

If I remember correctly in Rasa Inspector the error surfaced as user_input_too_long exception or failure to start Rasa Inspector.

Solution was to fix the version of httpx with:

pip install httpx==0.27.2

Happy coding!
