Why is my google custom search API call from python not working?

Question

When I run the following code I am getting an error response (see the second snippet). I have checked and made sure the GOOGLE_SEARCH_KEY and the SEARCH_ENGINE_ID are valid and I have billing set up properly. I have removed sensitive data from the error message and put in placeholders. What could be the issue? Thanks in advance.

            from googleapiclient.discovery import build

            try:

                api_key = GOOGLE_SEARCH_KEY
                search_engine_id = SEARCH_ENGINE_ID
                query = "test"
                num_results = 100

                service = build("customsearch", "v1", 
                         developerKey=api_key)

                response = service.cse().list(
                    q=query,
                    cx=search_engine_id,
                    num=num_results
                ).execute()
            except Exception as e:
                print(e)

Change num_results = 100 to num_results = 10.
