Error after pyscript update with a simple example code-CodePudding

I don't know if this error is due to a PyScript update, I would like to know how to solve it.

With previous versions there are no problems running the code using the following CDNs:

    <link rel="stylesheet" href="https://pyscript.net/alpha/pyscript.css" />

    <script defer src="https://pyscript.net/alpha/pyscript.js"></script>

The error occurs when I use the latest updated version (see CDNs) in the code below:

<html>

<head>

    <title> Learn DOM for PyScript </title>

    <link rel='stylesheet' type='text/css' media='screen' href='https://cdn.jsdelivr.net/npm/[email protected]/css/bulma.min.css'>

    <link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />

    <script defer src="https://pyscript.net/latest/pyscript.js"></script>

</head>
