when I try to get data from my API on IIS this error is shown

The 'ObjectContent`1' type failed to serialize the response body for content type 'application/json; charset=utf-8'."

this error is shown in my localhost also but when I wrote this code

var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
config.Formatters.Remove(config.Formatters.XmlFormatter);

the error is gone and the localhost is working fine right now,

http://192.168.137.1:5020/api/prodects

no data back just error

http://localhost:54740/api/prodects

data back and everything is fine

What am I missing?
