Typescript onPress With Promise Returned Error

I'm implementing typescript into my project for the first time and I have an error coming from onPress which calls toggleModal. The error is coming from onPress

According to the React Native docs, DatePickerAndroid.open() does the following:

Returns a Promise which will be invoked an object containing action, year, month (0-11), day if the user picked a date. If the user dismissed the dialog, the Promise will still be resolved with action being DatePickerAndroid.dismissedAction and all the other keys being undefined.

Can someone clarify if the error is coming from the following and how to fix it?

• The promise DatePickerAndroid.open() since it the response may or may not be returned
• Do I need to type onPress as a function with onPress: Function?
