Error in template while adding employee list

Hi I am getting error while adding the list of employee in template. Error:

The range does not meet the requirements of the list ranges. For details, see the documentation.

Please check the code: `
var people = new List<Employee> { new Employee {Name = “Alice”, Address = “dfsasdasdasd”,Phone=“312312312”}, new Employee {Name = “Alice1”, Address = “dfsasdasdasd1”,Phone=“2131232”}, new Employee {Name = “Alice3”, Address = “dfsasdasdasd3”,Phone=“5645”} }; template.AddVariable(“employee”, people); template.Generate(); template.SaveAs(outputFile); public class Employee { public string Name { get; set; } public string Address { get; set; } public string Phone { get; set; } }

` Please check the error screen shot. Template:

Output:

Note : for string and integer values it’s working fine. but issue with list
