🐛 Bug Report: useCounts hook crashes React Native app (Cannot read property 'filters' of undefined)

[AdzeB]

📜 Description

Using the useCounts hook from @novu/react-native in a React Native / Expo project causes the app to crash with the following error:

ERROR [TypeError: Cannot read property 'filters' of undefined]

This happens as soon as the hook is used in a component. The error appears to come from inside the Novu SDK, not from my own code, and suggests some internal object is undefined when the hook runs.

Environment:

• React Native (Expo managed)

  • "expo": "54.0.23"

  • "react-native": "0.81.5"

• Novu SDK:

  • "@novu/react-native": "^3.10.1"

👟 Reproduction steps

• Create a new Expo React Native project (managed workflow).

• Install Novu React Native SDK:

  npm install @novu/react-native

• Initialize Novu in your app (using your Novu app ID and subscriber ID), for example in App.tsx:

import React from 'react';
import { Text, View } from 'react-native';
import { NovuProvider } from '@novu/react-native';

export default function App() {
  return (
    <NovuProvider
      applicationIdentifier="<YOUR_APP_ID>"
      subscriberId="<YOUR_SUBSCRIBER_ID>"
    >
      <MainScreen />
    </NovuProvider>
  );
}

function MainScreen() {
  return (
    <View>
      <Text>Main</Text>
    </View>
  );
}

• In a child component rendered inside NovuProvider, use the useCounts hook:

import React from 'react';
import { Text, View } from 'react-native';
import { useCounts } from '@novu/react-native';

export function MainScreen() {
  const { data, isLoading, error } = useCounts();

  if (isLoading) return <Text>Loading…</Text>;
  if (error) return <Text>Error: {String(error)}</Text>;

  return (
    <View>
      <Text>Unread count: {data?.unseenCount}</Text>
    </View>
  );
}

• Run the app (e.g. npx expo start).

• The app crashes and logs:

  ERROR [TypeError: Cannot read property 'filters' of undefined]

👍 Expected behavior

The useCounts hook should work without crashing the app and should return counts (e.g. unseen/unread) according to the current subscriber and any configured filters. If something is misconfigured (e.g. missing provider), it should surface a clear error message instead of throwing Cannot read property 'filters' of undefined.

👎 Actual Behavior with Screenshots

• As soon as useCounts is used in a component, the app crashes.

• Error shown in the console / error overlay:

  ERROR [TypeError: Cannot read property 'filters' of undefined]
