Unknown error : Element 'script': The attribute 'src' is required but missing

[sibiar]

I am a newbie Magento2 developer and tried to develop shipping restriction country. So I created custom module which consists install data setup for creating custom product attribute. After that I had done the setup:upgrade and di:compile then static deploy too.

After that the error triggered

Now showing this error only not showing any php error to fix the issue

This is really unknown. I deleted the attribute and module. But still have the same error

    Install data script shows below
    
    namespace Vendor\Restrictproduct\Setup;
    
    use Magento\Eav\Setup\EavSetup;
    use Magento\Eav\Setup\EavSetupFactory;
    use Magento\Framework\Setup\InstallDataInterface;
    use Magento\Framework\Setup\ModuleContextInterface;
    use Magento\Framework\Setup\ModuleDataSetupInterface;
    
    class InstallData implements InstallDataInterface
    {
    private $eavSetupFactory;
    
    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }
    
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'shipping_restriction',
            [

Kindly check in your app/code or app/design for script or link tag.

Replace href attribute with src tag.

Example,

Replace

<link href="http://fonts.googleapis.com/css?family=Lato:100,300,400,700" rel="stylesheet" type="text/css"/>

with src

<link src="http://fonts.googleapis.com/css?family=Lato:100,300,400,700" rel="stylesheet" type="text/css"/>
