Failed to find ID. Ensure that you have an ID property on your model error in Sitecore Experience editor

Question

I have upgraded my Sitecore instance instance from Sitecore 8.2 to Sitecore 9.3

I am getting below errors in experience editor mode but in normal mode component is not showing because we added error handling pipelines for view and controller rendering.

Error in Text

Inner Exception Failed to find ID. Ensure that you have an ID property on your model.

My Code is

 public class TestViewModel
    {
        /// <summary>
        /// Gets or sets the id
        /// </summary>
        [SitecoreId]
        public Guid Id { get; set; }

       }

I have face same problem in my project, after some investigation I found that Glass Mapper properties needs to be virtual, so try below code and let me know if it's works for you or not.

 public class TestViewModel
   {
       /// <summary>
       /// Gets or sets the id
       /// </summary>
       [SitecoreId]
       public virtual Guid Id { get; set; }

      }
