[FIXED] Errors in executing javascript with perl Selenium::Remote::Driver

Issue

I am exploring Selenium::Remote::Driver - specifically running javascript.

However, in running this - which I think is pretty much the example in the documentation page:

use FindBin          qw( $RealBin );
use Selenium::Chrome qw( );

$\ = "\n"; $, = "\t"; 

my $web_driver = Selenium::Chrome->new(
   binary => "/usr/bin/chromedriver",
);

print $web_driver->has_javascript;

$web_driver->get($ARGV[0]);

my $script = q{
       var arg1 = arguments[0];
       var elem = window.document.findElementById(arg1);
      return elem;
   };
my $elem = $web_driver->execute_script($script,'hnmain');
print $elem;

I get this error:

Error while executing command: javascript error: javascript error: window.document.findElementById is not a function
  (Session info: chrome=120.0.6099.216) at /home/simone/perl5/perlbrew/perls/perl-5.30.2/lib/site_perl/5.30.2/Selenium/Remote/Driver.pm line 411.
 at /home/simone/perl5/perlbrew/perls/perl-5.30.2/lib/site_perl/5.30.2/Selenium/Remote/Driver.pm line 361.

Why is that? what am I doing wrong?

The line with print $web_driver->has_javascript;prints a true value.

Solution

findElementById

should be

getElementById
