While trying to change workflow task status to complete from Pending getting error "wf.status::status_condition(): AHD05724:Not a valid transition".
Service Desk Manager 17.x
It occurs if no status is defined or the selected task is invalid.
The error message "wf.status::status_condition(): AHD05724:Not a valid transition" is prompted due to following reasons:
1. Whenever a status should not be selected for a workflow status.
2. It does not exist in the behavior template list.
3. 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 task.
