Ios swift – Swift – No value associated with key CodingKeys

I run this error when I tried to parse a JSON response returned by an open API:

keyNotFound(CodingKeys(stringValue: "name", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: "name", intValue: nil) ("name").", underlyingError: nil))

This happens in the following line of code:
let decodedWeatherData = try decoder.decode(WeatherData.self, from: data)
And here’s the part of decoding codes:

func parseWeatherJSON(data: Data) {
    let decoder = JSONDecoder()
    
    do {
        let decodedWeatherData = try decoder.decode(WeatherData.self, from: data)
        let id = decodedWeatherData.weather[0].id
        let temp = decodedWeatherData.main.temp
        let name = decodedWeatherData.name
        
        let weather = WeatherModel(conditionId: id, temperature: temp, cityName: name)
        print(weather.tempStr)
    } catch {
        print(error)
    }
}

Here’s my JSON response:

{
  "coord": {
    "lon": 121.4692,
    "lat": 31.2323
  },
  "weather": [
    {
      "id": 800,
      "main": "Clear",
      "description": "clear sky",
      "icon": "01n"
    }
  ],
  "base": "stations",
  "main": {
    "temp": 25.48,
    "feels_like": 26.36,
    "temp_min": 23.86,
    "temp_max": 26.95,
    "pressure": 1011,
    "humidity": 87
  },
  "visibility": 10000,
  "wind": {
    "speed": 3,
    "deg": 140
  },
  "clouds": {
    "all": 0
  },
  "dt": 1695067161,
  "sys": {
    "type": 2,
    "id": 2043475,
    "country": "CN",
    "sunrise": 1695073210,
    "sunset": 1695117382
  },
  "timezone": 28800,
  "id": 1796231,
  "name": "Shanghai Municipality",
  "cod": 200
}

My structure of WeatherData:

struct WeatherData: Codable {
    let name: String
    let main: Main
    let weather: [Weather]
}

struct Main: Codable {
    let temp: Double
}

struct Weather: Codable {
    let description: String
    let id: Int
}

It seems my structure correspond to the JSON response. I don’t know why the decoding was failed and CodingKeys can’t be associated
