Research direction

Start by reproducing the error from app.js using the dependencies and versions listed in package.json, especially react-native 0.73.7 and react-native-drawer-layout 3.3.1. Trace where the undefined or null object is reported and compare the minimal Drawer example with the installed package behavior. Done should include a confirmed cause and a documented resolution, but the issue does not define a specific requested change.
