Liquid filter is returning null for workflow property's property

[weirdyang]

I have a Workflow property called message, I am trying to access the Id property using liquid filter:
{{ Workflow.Properties.message.Id }}, but this is returning null.

However when I use javascript property("message")["Id"] to set the property test it works.

I am on version 2.0, I believe this used to work before? am I doing something wrong?

  "state": {
    "Input": {},
    "Output": {},
    "Properties": {
      "messageId": 11,
      "message": {
        "Id": 11,
        "Topic": "1",
        "Body": "test",
        "IsProcessing": false,
        "Completed": false,
        "CreatedTime": "2025-01-11T10:35:38Z",
        "LastModified": "0001-01-01T00:00:00Z",
        "RetryCount": 0
      },
      "test": 11
    },

services.Configure<TemplateOptions>(o =>
{
    o.MemberAccessStrategy.Register<MessageItem>();
});
