TurboModuleRegistry.getEnforcing(...): 'ReactNativeOtpVerify' could not be found

Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.

Bug summary

Hi and first thank you for making this port of react-native-otp-verify 🙏

I'm getting this error at runtime:
[runtime not ready]: Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'ReactNativeOtpVerify' could not be found. Verify that a module by this name is registered in the native binary.

I added the dependency exclusion rule for iOS in react-native.config.js as prescribed.

Maybe my understanding of TurboModules is wrong but I think the issue here is that RN tries to load the module at runtime, and of course it's not present on iOS.

What worked for me is to move the iOSProxy logic into NativeReactNativeOtpVerify.ts itself rather than in the index.tsx, so TurboModuleRegistry.getEnforcing('ReactNativeOtpVerify') is never even called on iOS at all:

NativeReactNativeOtpVerify.ts

-export default TurboModuleRegistry.getEnforcing<Spec>('ReactNativeOtpVerify');
+
+// iOS is not supported - throw error on iOS
+const throwIOSError = (): never => {
+  throw new Error(
+    'react-native-otp-verify is only available on Android. iOS is not supported.'
+  );
+};
+
+// Create proxy for iOS that throws errors
+const iOSProxy = new Proxy(
+  {},
+  {
+    get() {
+      return throwIOSError;
+    },
+  }
+) as Spec;
+
+
+export default Platform.OS === 'ios'
+? iOSProxy
+: TurboModuleRegistry.getEnforcing<Spec>('ReactNativeOtpVerify');

index.tsx

-// iOS is not supported - throw error on iOS
-const throwIOSError = (): never => {
-  throw new Error(
-    'react-native-otp-verify is only available on Android. iOS is not supported.'
-  );
-};
-
-// Create proxy for iOS that throws errors
-const iOSProxy = new Proxy(
-  {},
-  {
-    get() {
-      return throwIOSError;
-    },
-  }
-) as Spec;
-
 const OtpVerify: Spec =
-  Platform.OS === 'ios'
-    ? iOSProxy
-    : ReactNativeOtpVerify
+  ReactNativeOtpVerify

Thank you for bringing this issue to my attention @melvynhills . This package is currently not supported for Expo but I will update it so that Expo users can also utilise it.

[melvynhills]

I'm not sure there's anything special about Expo here, react-native-config.js should be supported normally as it's mentioned here: https://docs.expo.dev/modules/autolinking/#exclude

Does it work for you on a bare RN 0.81/new architecture app on iOS at all?

I think just a conditional import of the native module like in my diff would suffice, and then we can get rid of the exclusion rule altogether, which also simplifies installation.

[pushpender-singh-ap]

Hi @melvynhills - This issue has been resolved. Please install the 1.2.0 version and remove the react-native.config.js related configuration from the project.

[melvynhills]

Perfect, thanks!
