[FTAMachado]

Issue detected in Elsa studio 3.4, using the code currently available in this repo.

Adding an HttpResult output variable (of type HttpRequest or Object) to an HttpEndpoint activity, followed by sending a POST request to it causes a
System.NotSupportedException: Serialization and deserialization of 'System.Type' instances is not supported.
