I have this code that prints out a command and also runs it from Perl. When I run the curl command from Perl the remote server, queried from the curl request, complains about an HTTP 400 error.

When I run the same command, copied from the Perl print statement, it runs fine and returns a JSON string.

This behavior happens on Linux and Windows with Strawberry Perl. Any ideas?

Here is the code: 
#!/usr/bin/perl

use strict;
use warnings;

use Data::Dumper;

my $command = <<'END';
curl 'https://tax-calculator-api.taxfoundation.org/taxcalc/tcja_submit
+' -H 'Origin: https://taxfoundation.org' -H 'Accept-Encoding: gzip, d
+eflate, br' -H 'Accept-Language: en-US,en;q=0.9' -H 'User-Agent: Mozi

END

print $command;

my $data = `$command` or die "$!\n";
print Dumper $data;
