public class inmeitem {       public string id { get; set; }       [jsonproperty(propertyname = "heartrate")]       public string heartrate { get; set; }       [jsonproperty(propertyname = "pulsewave")]       public string pulsewave { get; set; } }

i have follow code insert new item table:

you need ensure returning correct results insert function, i.e. expects return inserted item. don't need return inserted item, must return render client, or framework return 404 instead message "the item not exist".

the first example succeeds because context.execute returns inserted item. in second example, item not being returned block of code in .then() call.
