This question runs in a pre-configured Salesforce environment - no personal connection required.
Fetch current weather conditions from the OpenWeatherMap API for given coordinates. Take latitude and longitude as parameters, make an HTTP callout to OpenWeatherMap API, parse the weather description from the JSON response, and return the current weather description as a string.
Use the OpenWeatherMap API endpoint https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid={API_KEY} to get weather data. Extract the description field from the first weather object in the response. Handle API errors gracefully by returning appropriate error messages.
Examples:
Input: latitude = 40.7128, longitude = -74.0060
Output: "clear sky"
Explanation: Current weather description for New York coordinates
Input: latitude = 51.5074, longitude = -0.1278
Output: "overcast clouds"
Explanation: Current weather description for London coordinates
Input: latitude = 999, longitude = 999
Output: "Error: Invalid coordinates"
Explanation: Invalid coordinates outside valid range
