I’m trying to update an inherited project from SDK 28 to SDK 37, and am running into an error on the iOS simulator which I can’t quite figure out.
Invariant Violation: Native module cannot be null.
There isn’t much in the way of logs, either in the terminal running expo start -c
or in the browser tab that command opens up. On the simulator, there’s something of a stack but I’m not really able to understand it.
constructor (NativeEventEmitter.js:36:16)
<global> (index.js:5)
loadModuleImplementation (require.js:322:6)
<unknown> (AppEntry.bundle?platform=...=false&hot=false:128811:65)
loadModuleImplementation (require.js:322:6)
<global> (AppEntry.js:3)
loadModuleImplementation (require.js:322:6)
guardedLoadModule (require.js:201:45)
global code (AppEntry.bundle?platform=...y=false&hot=false:261916:4)
Double-clicking that <global> (index.js:5)
entry in the simulator brings up node_modules/react-native-appsflyer/index.js, the first few lines of which are:
1: import {NativeEventEmitter, NativeModules} from "react-native";
2:
3: const { RNAppsFlyer } = NativeModules;
4: const appsFlyer = {};
5: const eventsMap = {};
6: const appsFlyerEventEmitter = new NativeEventEmitter(RNAppsFlyer);
