Models with GUID properties + JSON.stringify() == Cyclic reference detected

Hi,

I'm starting a project with Elsa Workflows and I'm facing an issue with Work Flow Context. The models I'm using is using Guid for primary key data type. Using the sample ElsaGuides.WorkflowContexts.Web project, I tried changing,

    public class BlogPost
    {
        public string Id { get; set; } = default!;
        public string Title { get; set; } = default!;
        public string Body { get; set; } = default!;
        public bool IsPublished { get; set; }
    }

to

    public class BlogPost
    {
        public Guid Id { get; set; } = default!;
        public string Title { get; set; } = default!;
        public string Body { get; set; } = default!;
        public bool IsPublished { get; set; }
    }

and updated BlogPostWorkflowContextProvider to reflect the change above, I'm now getting the following error,

    {
        "errorMessage": "Workflow faulted at 2023-05-29T07:45:16Z with error: An exception was thrown whilst setting 'WriteHttpResponse.Content'. See the inner exception for further details.",

                    "Expression": "const model = {\r\n    blogPost: workflowContext,\r\n    workflowInstanceId: workflowInstanceId\r\n}\r\n\r\nreturn JSON.stringify(model, null, 2);",
                    "Syntax": "JavaScript"
                }
            },
            "Data": {}
        },
        "workflow": {
            "name": null,
            "version": 5,
            "instanceId": "9f192ad6d0454a2298ad966115695044"
        }
    }

I found that the cause of the issue is the JSON.stringify() function call in the first WriteHttpResponse due to Id being Guid data type. I tried returning the model constant directly in the Content and it execute fine.

May I know how to resolve this with JSON.stringify()?
