i am to declare Body as JsonElement and inspect its properties to parse the contained value as string or string[], depending on the token type. but I am stuck. My body response from elasticsearch can be string or string[] but my data model only set as string[]. below are my snippet

Model:

public class ElasticsearchData
    {
        [JsonPropertyName("title")]
        public string Title { get; set; }
        [JsonPropertyName("url")]
        public string Url { get; set; }
        [JsonIgnore]
        public string[] Body { get; set; }
        [JsonPropertyName("creation_time")]
        public string Creation_Time { get; set; }
        [JsonIgnore]
        public int NumberOfDoc { get; set; }

        public ElasticsearchData()
        {
            Title = string.Empty;
            Url = string.Empty;
            Creation_Time = string.Empty;
            NumberOfDoc = 0;
        }
    }

Snippet:

                {
                    Query = new MatchQuery("body")
