react-native-webview Typescript error: 'WebView' cannot be used as a JSX component

Question

I am trying to set up a simple React Native app using Expo with TypeScript that shows a WebView. My App.tsx file contains the following:

import Constants from 'expo-constants';
import { StyleSheet } from 'react-native';
import { WebView } from 'react-native-webview';

export default function App() {
    return (
        <WebView
            style={styles.container}
            source={{ uri: 'https://example.com/' }}
        />
    );
}

const styles = StyleSheet.create({
    container: {
        marginTop: Constants.statusBarHeight,
    },
});

This code works correctly, but the TypeScript compiler throws an error at the WebView component.

App.tsx:7:4 - error TS2786: 'WebView' cannot be used as a JSX component.
  Its instance type 'WebView<{ style: { marginTop: number; }; source: { uri: string; }; }>' is not a valid JSX element.
    The types returned by 'render()' are incompatible between these types.
      Type 'import("C:/example/node_modules/@types/react/index").ReactNode' is not assignable to type 'React.ReactNode'.
        Type '{}' is not assignable to type 'ReactNode'.
          Type '{}' is missing the following properties from type 'ReactPortal': key, children, type, props

Found 1 error.

I am using the following versions of my dependencies:

{
    "dependencies": {
        "expo": "~44.0.0",
        "expo-status-bar": "~1.2.0",
        "react": "17.0.1",
        "react-dom": "17.0.1",
        "react-native": "0.64.3",
        "react-native-web": "0.17.1",
        "react-native-webview": "11.15.0"
    },
    "devDependencies": {
        "@babel/core": "^7.12.9",
        "@types/react": "~17.0.21",
        "@types/react-native": "~0.64.12",
        "typescript": "~4.3.5"
    }
}

How can I correct this error?

Answer 1

You would get this error if you had more than one @types/react library in your node_modules. In my case this was caused by Storybook which included @reach/router which included @types/reach__router which included @types/react@18 different from my current Expo version.

Using How do I override nested dependencies with `yarn`?

I added the matching version

  "resolutions": {
    "@types/react": "~17.0.21"
  },

and regenerated to get rid of the error.
