I can't get the highlight_node-function to work.
Error message is
Odd name/value argument for subroutine 'WWW::Mechanize::Chrome::eval_in_page' at C:/Strawberry/perl/site/lib/WWW/Mechanize/Chrome.pm line 2001.
Here is an example code

use strict;
use warnings;
use Log::Log4perl qw(:easy);
use WWW::Mechanize::Chrome;
 
my $mech = WWW::Mechanize::Chrome->new;
$mech->get('https://metacpan.org/');
sleep(1);
my @nodes = $mech->xpath('//p');
$mech->highlight_node($mech,@nodes);
sleep(3);

A workaround that seems to work for me is to use 'callFunctionOn'-function provided by WWW::Mechanize::Chrome and use same JavaScript as original code

highlight_nodes(@nodes);

sub highlight_nodes {
    my @nodes = @_;
    foreach my $node (@nodes) {
        my $objectId = $$node{objectId};
        $mech->callFunctionOn(
            'function() {
                if( "none" == this.style.display ) {
                    this.style.display= "block";
                };             
                this.style.backgroundColor = "red";
                this.style.border = "solid black 1px" 
             }',
             objectId => $objectId,
             arguments => []
        );
    }    
}
