The problem is that $remedyqueue doesn't contain an array (or better an array reference), but an XML::XPath::NodeSet object. You need to turn it to an array by using the get_nodelist method, but it returns a list of objects, so you need to convert them to something simpler - as you haven't shown the input XML, we can only guess, in my example, I used the string_value method: 
#!/usr/bin/perl
use warnings;
use strict;

use XML::XPath;
use JSON;

my $dom = 'XML::XPath'->new(xml => '<r><a>1</a><a>2</a><a>3</a></r>');

my $remedy_queue = $dom->find('/r/a');

print encode_json([ map $_->string_value, $remedy_queue->get_nodelist 
+]), "\n";

Output: 

["1","2","3"]

BTW, if the newline comes last in the values, you can replace $var =~ s/\n//; by more common 

chomp $var;
