Api Call Fails with 500 despite returning Data

Question

The below code is failing with "the server responded with a status of 500 ()"

But data is being populated in elevation, I am trying to populate the elevation in browser using ajax call

but couldn't succeed.

https://api.open-meteo.com/v1/elevation?latitude=52.52&longitude=13.41

https://open-meteo.com/en/docs/elevation-api

string urlel = $"https://api.open-meteo.com/v1/elevation?latitude={data.latitude}&longitude={data.longitude}";
            var responseel = client.GetAsync(urlel).Result;
            string jsonel = await responseel.Content.ReadAsStringAsync();
            dynamic datael = Newtonsoft.Json.JsonConvert.DeserializeObject(jsonel);
            int elevation = datael.elevation;

Answer 1

your sample url returns

{
    "elevation": [
        38.0
    ]
}

so elevation is an array of numbers, not an int. try:

double elevation = datael.elevation[0];
