LINQ Reporting engline throws System.InvalidOperationException using C#

I have used foreach tag in word template to iterate list of objects,
Current Scenario: I am creating dynamic class at run time that class can have properties like List SWSolution {get; set;} where SWSolution is a class, now if i get empty list in response like {SWSolution: []}, then i will not be able to create a class as i will not be having any properties for that, so i am setting property type as List SWSolutoin and set its value to empty list,

dynamically created class will look like this:

Public class DynamicClass {
public List SWSolution {get; set;}

When i pass this object of dynamic class to our engine as
engine.BuildReport(document, dynamicClassInstance, “tableList”);

it gives me error saying:
“Message”: “An error has occurred.”,
“ExceptionMessage”: “An error has been encountered at the end of expression '(a. PurchaseOption”’. Can not get the value of member ‘PurchaseOption’ on type ‘System.Object’.",
“ExceptionType”: “System.InvalidOperationException”,

here how i am accessing SWSolution in my template :

Even if condition applied on table is false it check for SWSolution properties.
How can we avoid to access properties when List is empty?
Please do some needful.

I found similar query, here is the link Can not iterate over an instance of type ‘System.Object’. ’
