Sorry for hijacking the thread, my issue is on the SES::call_ses side. If I shift $self I get an error about an empty hash for %$opts, if I don't shift $self it works. This works: 
sub call_ses {
    my $params = shift;
    my $opts = shift;

    %opts = %$opts;
    %params = %$params;

    my $endpoint_name = $endpoint;
}

This doesn't: 
sub call_ses {

    my $self = shift;

    my $params = shift;
    my $opts   = shift;

    %opts   = %$opts;  <-- Line 559
    %params = %$params;

   my $endpoint_name = $self->AWS_endpoint;

}

Can't use an undefined value as a HASH reference at

    (F) A value used as either a hard reference or a symbolic referenc
+e must
    be a defined value.  This helps to delurk some insidious errors.

Should I abandon $self and just call the subs like I did in the working version? Thanks to the Monastery for all the years of saving my butt as I stumbled through PERL.
