Ah it's this line -

App/src/pages/iou/IOUCurrencySelection.js

Line 117 in e7a17f8

onBackButtonPress={() => Navigation.goBack(ROUTES.getIouRequestRoute(Navigation.getTopmostReportId()))}

- ROUTES.getIouRequestRoute() doesn't actually exist. Need to figure out what it's supposed to do and fix it...
