Missing Paws::Credential::None Usage

[cakirkeMSTS]

at current, the module references Paws::Credential::None here

p5-paws-credential-webidentity/lib/Paws/Credential/AssumeRoleWebIdentity.pm

Line 5 in b229812

use Paws::Credential::None;

but doesn't use it.

this results in unexpected default behavior with the STS object trying the built in Paws::Credential::ProviderChain and failing.

i tested locally by changing:

has sts => (
    is      => 'ro', 
    isa     => 'Paws::STS', 
    lazy    => 1, 
    default => sub {
        my $self = shift;
        Paws->service('STS', 
            region      => $self->sts_region
        );
    }
);

to:

has sts => (
    is      => 'ro', 
    isa     => 'Paws::STS', 
    lazy    => 1, 
    default => sub {
        my $self = shift;
        Paws->service('STS',
            credentials => Paws::Credential::None->new,
            region      => $self->sts_region
        );
    }
);
