Describe the bug

  • Execute npx create-react-app test --template typescript

import "./App.css";

function App() {
  useEffect(() => {
    axios.get("https://jsonplaceholder.typicode.com/posts");
  }, []);
  return (
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.tsx</code> and save to reload.
        </p>
        <a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
