Type '{}' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes

i am currently making a simple react application. this is my index.tsx

import * as React from 'react';
import * as ReactDOM from 'react-dom';
import App from './components/App';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(
  <App />,
  document.getElementById('root') as HTMLElement
);
registerServiceWorker();

and here I have my app.tsx

    import * as React from 'react';
import SearchBar from '../containers/price_search_bar';

interface Props {
  term: string;
}

class App extends React.Component<Props> {

  // tslint:disable-next-line:typedef
  constructor(props) {
    super(props);
    this.state = {term: '' };
  }

  render() {
    return (
      <div className="App">
        <div className="App-header">
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro">
          this is my application.
        </p>
        <div>
            <form>
            <SearchBar term={this.props.term} />
            </form>
        </div>
      </div>
    );
  }
}

export default App;

and also my search bar container:

    import * as React from 'react';

interface Props {
    term: string;
}

// tslint:disable-next-line:no-any
class SearchBar extends  React.Component<Props> {

    // tslint:disable-next-line:typedef
    constructor(props) {
        super(props);
        this.state = { term: '' };
    }

    public render() {
        return(
            <form>
                <input 
                    placeholder="search for base budget"
                    className="form-control"
                    value={this.props.term}
                />
                <span className="input-group-btn" >
                    <button type="submit" className="btn btn-secondary" >
                        Submit
                    </button>
                </span>

            </form>
        );
    }
}

export default SearchBar;

and finally I have my tsconfig.json:

{
  "compilerOptions": {
    "outDir": "build/dist",
    "module": "esnext",
    "target": "es5",
    "lib": ["es6", "dom"],
    "sourceMap": true,
    "allowJs": true,
    "jsx": "react",
    "moduleResolution": "node",
    "rootDir": "src",
    "forceConsistentCasingInFileNames": true,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "noImplicitAny": false,
    "strictNullChecks": true,
    "suppressImplicitAnyIndexErrors": true,
    "typeRoots": [
      "node_modules/@types"
    ],
    "noUnusedLocals": true
  },
  "exclude": [
    "node_modules",
    "build",
    "scripts",
    "acceptance-tests",
    "webpack",
    "jest",
    "src/setupTests.ts"
  ]
}

I keep getting different errors after errors and when ever I fix one error another one appears, I am not sure what I have done that make it behave like this. This is the latest error:

./src/index.tsx
(7,3): error TS2322: Type '{}' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<App> & Readonly<{ children?: ReactNode; }> & Reado...'.
  Type '{}' is not assignable to type 'Readonly<Props>'.
    Property 'term' is missing in type '{}'.

I tried to fix it by modifying my tsconfig.json but the same error still appears, what am I doing wrong and why typescript is bahing like this. I am very new to this and by this example I am trying to udnertand how react works all together.

I solved a lot of "not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes" type of errors (Microsoft closed issue) just by declaring an object that is passed entirely to the component.

With the OP's example, instead of using term={this.props.term}, use {...searchBarProps} to get it working:

render() {
  const searchBarProps = { // make sure all required component's inputs/Props keys&types match
    term: this.props.term
  }
  return (
    <div className="App">
      ...
      <div>
          <form>
          <SearchBar {...searchBarProps} />
          </form>
      </div>
    </div>
  );
}
