This includes activities such as creation or deletion of new or existing status, transitions, node, event or action in both your Freshservice account and Sandbox account. Sync errors cannot be fixed easily like conflict errors.
For eg: When a transition is added to the status (Pending Review -> Closed) in your Sandbox account and a transition has been added to the same status (Pending Review -> Open) in your Freshservice account as well. This will lead to a Sync Error.
Note: Sync errors can happen only in Workflow Automator and Change Lifecycle.
