Check the render method of `Drawer Sidebar`

问题

I'm using React-navigation module, and I Created DrawerContent and I Got this Error:
Check the render method of "Drawer Sidebar"
How Can I Fix this Error?

Default Code is ok:
contentComponent: props => <ScrollView><DrawerItems {...props} /></ScrollView>

My new Code is Not ok:
contentComponent: DrawerContent
and
const DrawerContent = (props) => (<ScrollView><DrawerItems {...props} /></ScrollView>)

I opened This Issue too: (https://github.com/react-community/react-navigation/issues/2175)
