Using Validate to Find Missing Artifacts in Navigation Flows
While viewing the Navigation Flow listing, you might see navigation flow nodes or
                artifacts displaying an error icon  . This error occurs because artifacts that were associated with the
                navigation flow were either renamed or removed and they are now considered missing.
                You'll need to edit the navigation flow to associate it with either a renamed
                artifact or with a different artifact before you can activate the navigation flow.
                You might not realize that artifacts are considered missing, so it's recommended
                that you validate your navigation flows before setting them to Active status.
