I have gone through some of the trouble shooting posts for getting started on connecting to the TMDB API

I have made sure that my API key is valid by testing on my web browser to see if I get the JSON text for Star Wars using this URL https://api.themoviedb.org/3/movie/550?api_key=YOUR_API_KEY, which does give me the JSON text for Star Wars back.

However, even when I use the 'try it!' code on the tmdb getting started page with my valid API key, as well as running the code on Jupyter Notebook Python Version 3.10.9. I get "status_message": "Invalid API key: You must be granted a valid key."
