It seems networkStatus doesn't provide a connectivity attribute and PlasmaNM.NetworkManager doesn't have a Full either:
console.log(Object.keys(networkStatus)) qml: [objectName,activeConnections,networkStatus,objectNameChanged,activeConnectionsChanged,networkStatusChanged]
networkStatus.connectivity !== PlasmaNM.NetworkManager.Full .../contents/ui/main.qml:150: TypeError: Cannot read property 'Full' of undefined
