# How to fix react-intl missing message error in React?

If you're encountering a "missing message" error in your React application that uses [react-intl](https://www.npmjs.com/package/react-intl) for localization, don't panic! This error is actually expected behavior if some of your localization messages are missing.

In fact, these errors can be helpful in identifying which messages are missing and need to be added to your project.

If you want to change how missing messages are handled in your application, you can use the `onError` prop on the `IntlProvider` component. However, this should be used with caution and only if you know what you're doing. Changing the error handling behavior can potentially hide important issues that need to be addressed, so it's important to carefully consider any changes you make.

```javascript
<IntlProvider locale={locale} messages={messages} onError={(error) => { /* Handle missing message... */ }}>
  <App />
</IntlProvider>
```
