I am able to save a very simple workflow but get the following error when attempting to publish it: "Error publishing workflow. Workflow XAML failed validation due to the following errors: The private implementation of activity '1: DynamicActivity' has the following validation error: Value for a required activity argument 'Operand' was not supplied. HTTP headers received from the server - ActivityId: c029b60f-5b33-462a-856d-4545464f1a6a. NodeId: . Scope: . Client ActivityId : 79a2839d-3013-3000-08dc-17016a223847. The remote server returned an error: (400) Bad Request."
Please note I have checked all actions and they have been configured. I'm currently using a trial version which has 17 days left. What does this error mean and how can I publish a workflow please?
