I am trying to fetch IATA codes from the Amadeus API and fill my Google Sheets’ column with that data (100 Days of Code: The Complete Python Pro Bootcamp, day 39)

My code is:

def get_destination_code(self, city_name):


IATA_ENDPOINT = "https://test.api.amadeus.com/v1/reference-data/locations/cities"
query = {
            "keyword": city_name,
            "max": "2",
            "include": "AIRPORTS",
        }
        city_header = {
            "Authorization": "Bearer " + self._token
        }
        response = requests.post(
            url=IATA_ENDPOINT, headers=city_header, params=query)

        print(f"Status code {response.status_code}. Airport IATA: {response.text}")
        try:
            code = response.json()["data"][0]['iataCode']
        except IndexError:
            print(f"IndexError: No airport code found for {city_name}.")
            return "N/A"
        except KeyError:
            print(f"KeyError: No airport code found for {city_name}.")
            return "Not Found"

        return code

I am passing cities like Paris, Frankfurt, Tokyo, Hong Kong but I am getting this error:

Status code 500. Airport IATA: 
            {
                "errors": [
                            "code": 38189,
                            "title": "Internal error",
                            "detail": "An internal error occurred, please contact your administrator",
                            "status": 500
                        }
                ]
            }

What can I do?

I have changed the city names in uppercase, but it didn’t work.
