Bug with saml_url ?

[piep14]

Hello,

I've tried these different formats:

$url = saml_url(config('app.url'), $identity->uuid, [config('app.url') . '/login-sso-redirect']);
$url = saml_url(config('app.url'), $identity->uuid, config('app.url') . '/login-sso-redirect');
$url = saml_url(config('app.url'), $identity->uuid, ['returnTo' => config('app.url') . '/login-sso-redirect']);

But the result is still the same, and without my return parameter.
