Invalid character found in method name. HTTP method names must be tokens, persists even with http request - perl

Question

I am trying to warm up my controller so that the service gets hot during each deployment.
In order to do this i have written a perl script as below:
#!perl
use strict;
use warnings;
use WWW::Mechanize;
use HTTP::Request;
my $ua = WWW::Mechanize->new();
my $r = HTTP::Request->new(
'GET' =>
'http://gaurav_setia.microsoft.com:8080/b2h/homepage?_encoding=UTF8&opf_redir=1&portalDebug=1',
[
'Connection' => 'Keep-Alive',
'Via' => 'HTTP/1.1 ShoppingSchedule',
'Accept' =>
'text/x-html-parts,text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
'Accept-Charset' => 'UTF-8',
'Accept-Encoding' => 'identity',
'Accept-Language' => 'en-US',
'Host' => 'gaurav_setia.microsoft.com',
'User-Agent' =>
'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.80 Safari/537.36',
'Cookie' =>
'Original-X-Forwarded-For' => '10.45.103.166',
'X-MS-Internal-Ip-Class' => 'rfc1918',
'X-MS-Internal-Via' =>

'X-MS-Urlspace' => 'NoPageType',

'X-MS-Portal-Page-Type' => 'AQGate',
'X-MS-Portal-Request-Attr' => 'internal, http, portal-debug',
'X-MS-Portal-Session-Id' => '1M0-493PO66-0596753',
'X-MS-Portal-Ubid' => '1P2-465OP632-8831161',
'X-MS-Portal-User-Attr' => 'business',
'X-MS-Rid' => 'G308MPK95BWTA69EY2MW',

'X-Forwarded-Host' => 'development.ms.com',
'X-Forwarded-Server' =>
'development.ms.com, b-hp-shpomnpng-na-2b-02af3555.us-west-2.amazon.com',
'X-Original-Args' => 'portalDebug=1',
'X-Original-Method' => 'GET',
'X-Original-Scheme' => 'http',
'X-Original-Uri' => '/',
],
);
my $res = $ua->request( $r, );
if ( $res->is_success() )
{
print $response->is_success();
}
print $response->status_line;
This script should run after each deployment.
But in the catalina.out logs i am getting the following error:
Dec 13, 2018 9:08:11 AM org.apache.coyote.http11.AbstractHttp11Processor process
INFO: Error parsing HTTP request header

I am unable to find the fix!
Many answers say that this is due to https/http issue, but i am making a http call here itself!

Answer 1

In amongst your pile of headers, you have this:
'User-Agent' =>
'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.80 Safari/537.36',
'Cookie' =>
'Original-X-Forwarded-For' => '10.45.103.166',
Notice that there's no value for the Cookie header. That means all of the headers after that will be wrong (the names and values will be muddled up).
Either remove the Cookie line completely or set its value to undef.
'Cookie' => undef,
(Removing it is probably best)
