React Native: Build does not fail on TypeScript error

How can I make the React Native CLI fail on a TypeScript error?

    const getCatOfTheDay = (cat: string) => `Cat of the day: ${cat}`;

This should throw a TypeScript error

Argument of type 'number' is not assignable to parameter of type 'string'.ts(2345)

but instead my npm start does just continue working and doesn’t throw any error.

My tsconfig.json

    "compilerOptions": {
        "allowSyntheticDefaultImports": true,
        "forceConsistentCasingInFileNames": true,
        "jsx": "react-native",
        "module": "commonjs",
        "noEmit": true,
        "noEmitOnError": true,
        "strict": true,
        "target": "ES2020"
