fivefilters\Readability\Nodes\DOM\DOMNodeList::add(): Argument #1 ($node) must be of type

[liorphp]

Hello.
I am getting this Unhandled error:

fivefilters\Readability\Nodes\DOM\DOMNodeList::add(): Argument #1 ($node) must be of type fivefilters\Readability\Nodes\DOM\DOMNode|fivefilters\Readability\Nodes\DOM\DOMElement|fivefilters\Readability\Nodes\DOM\DOMText|fivefilters\Readability\Nodes\DOM\DOMComment, fivefilters\Readability\Nodes\DOM\DOMProcessingInstruction given, called in /var/www/.../public_html/VendorPhp/fivefilters/readability.php/src/Nodes/NodeUtility.php on line 161

How can I resolve this?

Thank you, we'll have a fix soon. If you're able to provide the HTML that caused this, please attach it or link to it so we can test it against the rest of the code too.

We are experiencing this error a lot as well.

DOMProcessingInstruction represents tags like:

<?xml-stylsheet ... ?>
<?php ... ?>

You can find, and remove, all processing instructions using xpath:

//processing-instruction()

Thanks! This should be fixed in version 3.3.1. Let us know if you notice any other issues.
