Deserialize an Object from JSON API - Unexpected character encountered while parsing value: {. Path '[0].produced_weight', line 1, position 295

Im retrieving JSON format data from an API URL like: https://example.help/api/a?start_date=2022-09-01&end_date=2022-09-13&apikey=123 And i'm using to get the data:

public string Get(string url, string json, Contexto oContexto)
    {
        try
        {

            var client = new RestClient(url);
            var request = new RestRequest(Method.GET);
            IRestResponse response = client.Execute(request);
            return response.Content;
        }
        catch (Exception oExcepcion)
        {
            ErrorControl oErrorControl = new ErrorControl();
            oErrorControl.RecordErrorLog(System.Reflection.MethodBase.GetCurrentMethod().Name, oContexto.Request, oContexto.UserIdentity, oExcepcion);
            return string.Empty;
        }
    }

And when im trying to deserialize the data with

oListTransparency = JsonConvert.DeserializeObject<List<ReportTransparency>>(datos);

I'm getting this error Unexpected character encountered while parsing value: {. Path '[0].produced_weight', line 1, position 295. The variable datos is an String with the text format of the JSON

The JSON looks like this:
