Can you provide the URL for the Public Workspace that you’re working in please?

I don’t have access to the latest course notes for this.
The only request that appears to relate is the “skill check” request.
It’s the only request that appears to allow a “movieName”. All of the other requests relates to books.
That request will accept a JSON body, and a query parameter. (You are missing one of these elements).
As this is meant to be a learning exercise, I would recommend re-reading the instructions for the skill check.
