[Bug] ELSA 3.2.1 Serialization of workflow instances / Object list properties with MongoDb no longer working, circular references...

[JochenSteinbrenner]

Description

I have created a custom function findEntities which returns a List<ExpandoObject> within Jint engine.
With Version ELSA 3.2, I can call the function within a JavaScript activity. The result can be persisted within a variable using
the setVariable(..) method. For example:
setVariable("MyArray", findEntities("x => x.Template != null"));
The MyArray variable is correctly persisted within the WorkflowState.

After update to Version ELSA 3.2.1, this leads to Maximum serialization depth exceeded within WorkflowInstance persistence...
Refer to attached log file...

Error: An error occurred while serializing the WorkflowState property of class Elsa.Workflows.Management.Entities.WorkflowInstance: An error occurred while serializing the ActivityExecutionContexts property of class Elsa.Workflows.State.WorkflowState: An error occurred while serializing the Properties property of class Elsa.Workflows.State.ActivityExecutionContextState: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: An error occurred while serializing the Parent property of class System.Text.Json.Nodes.JsonNode: Maximum serialization depth exceeded (does the object being serialized have a circular reference?).'

At the moment, within ELSA 3.2.1 it is impossible to persist any arrays within a workflow instance variable

Are the any breaking changes within WorkflowInstance Persistance? Critical bug?

Steps to Reproduce

Try to store an array property using the JavaScript activity and the setVariable method. For example

• Add JavaScript activity to workflow
• Create the Variable: MyArray with type object and WorkflowInstance persistance
• Call script:

let myArray = ([
    1,2,3,4,5,6
])
setVariable("MyArray", myArray);

Reproduction Rate:

• No error with ELSA 3.2
• Always with ELSA 3.2.1

Still bugs in serialization within version 3.2.3. This breaks my whole program :(
