Invariant Violation: "myAppName" has not been registered

[mantegnous]

Description

i'm trying to running on ios emulator, but without success:

Invariant Violation: "myAppName" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called., js engine: hermes

metro is started, and build, so i think the problem is:

• A module failed to load due to an error and AppRegistry.registerComponent wasn't called., js engine: hermes

Version

0.70.2

[sam-houle1]

@mantegnous did you fix the issue ? I'm having the same problem, solving the deprecated-react-native-prop-types issues did not help.

[AlessioCamm]

Someone has fix this issue ? I got the error with Android, but not with iOS.

[RalissonMattias]

I'm getting this on RN 0.71, any solution?

[sam-houle1]

I had this issue on 0.88.5, but the reason I had this error is because I'm using wix/react-native-navigation, I had to enter npx rnn-link to resolve this issue.

Could also be because in some native file, the project name is still have some rndiffapp in some native file.

[Yeasirarafat53]

I am getting the same error after upgrading to react native 0.71.4

[student513]

same here

[muzhaqi16]

Check the info before the error; that should tell you what's causing it. For me, it was react-native-reanimated.

 Error: Exception in HostFunction: java.lang.NoSuchMethodError: no non-static method "Lcom/swmansion/reanimated/NativeProxy;.registerEventHandler(Lcom/swmansion/reanimated/nativeProxy/EventHandler;)V", js engine: hermes

[allanrosero]

[brettbl]

I getting the same issue except my issue doesn't appear to be related to the js engine: hermes. @ErickJ3 solution did not work for me. I'm running 0.71.4 and testing and iOS app.

[vivkikkk]

Check the App name in MainActivity at getMainComponentName function, app.json, and package.json it will same in these 3 places.

[Chuabacca]

Check the App name in MainActivity at getMainComponentName function, app.json, and package.json it will same in these 3 places.

@methineeinkan After using the Upgrade Helper to go to 0.71.6, I had the wrong moduleName in my AppDelegate.mm file. Thanks!

[g-wozniak]

Maybe it's trivial, but make sure your app.config.js or app.json contains "expo" property in the JSON/JS object. In my case it was missing and produced an error "ReferenceError: Property 'TextEncoder' doesn't exist, js engine: hermes" and A module failed to load due to an error and AppRegistry.registerComponent wasn't called., js engine: hermes. I took the config example from somewhere where it wasn't defined. So keep: {"expo": {"name": "xxx", ...}}

[thanhdat2106]

I'm getting the same error, anyone have any solution?

[Ali-Rzaa]

I got the same error in mac for ios and solved it by running $ cd ios $ pod install $ cd .. and then started the metro by cleaning cache using following command $ npm start --reset-cache
