Uncaught TypeError

I get an Uncaught TypeError:

> index.php.js:10 Uncaught TypeError: Cannot read properties of null (reading 'dataset')
>     at index.php.js:10:377613

vite.config.js contains:

```js
    usePHP({
      entry: [
        'index.php',
      ]
    })
```

But I'm sure if the `entry` is really needed.
