Question:
Why the error message "wf.status::status_condition(): AHD05724:Not a valid transition" occurs?
Answer:
The error message "wf.status::status_condition(): AHD05724:Not a valid transition" is prompted, whenever there is a status that should not be selected for a workflow status, due to the fact that it does not exist in the behavior template list or because it is a value that can't be selected like "Cancelled", which is only set when the ticket or CO is "Cancelled"

It is necessary to ensure that the category workflow tasks have valid behavior templates for each tasks otherwise this kind of error will occur, additional information can be found in the official documentation.
