SSO SAML And OAuth Support

Your software
My Mautic version is: 5.x
My PHP version is:8.1
My Database type and version is: MariaDB 10.5.9

Your problem
My problem is: Trying to use SAML to log in

These errors are showing in the log:
[2024-09-12T15:26:39.649694+00:00] mautic.CRITICAL: Uncaught PHP Exception ArgumentCountError: “LightSaml\SpBundle\Controller\DefaultController::__construct(): Argument #1 ($metadataProfileBuilder) not passed” at /home/my.url.net/public_html/vendor/lightsaml/sp-bundle/src/LightSaml/SpBundle/Controller/DefaultController.php line 29 {“exception”:“[object] (ArgumentCountError(code: 0): LightSaml\SpBundle\Controller\DefaultController::__construct(): Argument #1 ($metadataProfileBuilder) not passed at /home/campaign.imatr.net/public_html/vendor/lightsaml/sp-bundle/src/LightSaml/SpBundle/Controller/DefaultController.php:29)”} {“hostname”:“myweb.url.net”,“pid”:1752133}
Steps I have tried to fix the problem:
looked through the logs
Setup authentik sso with SAML 2.0 provider - should I be using SAML Metadata Provider instead? Created the metadata xml file -uploaded to mautic and added the cert and private key.
I get the following each time:

Anyone able to use SSO SAML successfully?

Is it possible to hire a mautic dev to fix or configure this to work on our system?
