Real-time workflows and action processes do not create system job records. Any errors that occur will be displayed to the user in their app with the heading Business Process Error.
Moreover, in a real-time workflow, there is no log for successful operations. You can enable Error logging by checking the keep logs for workflow jobs that encountered errors during setting. You will find this setting in the Workflow Log Retention area in the process editor.
If you want a view of the errors, use Advanced Find, and create a view for the Process Session entity.
