React shows warning in console if I use React.Fragment
```
Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.
```

    const parentName =
      typeof parentType === 'string'
        ? parentType
        : parentType.displayName || parentType.name;

      info = `\n\nCheck the top-level render call using <${parentName}>.`;
    }
  }
  return info;
}
