SAML - Class "LightSaml\Meta\ParameterBag" not found

[tom]

Hello,
in version 2023 i used saml to log into my project. After updating to 2024.8, this no longer works. Do I need to indicate an additional setting?

here my log:

[ log.DEBUG: Initialize PHPMaker2024\myproject\Saml2, config:  {"enabled":true,"adapter":"PHPMaker2024\\myproject\\Saml2","idpMetadata":"https://login.microsoftonline.com/***********************/federationmetadata/2007-06/federationmetadata.xml?appid=******************","entityId":"organisatie","certificate":"","privateKey":"","color":"success","callback":"https://projectsite/login/Saml","debug_mode":false,"debug_file":""} []

According to the Azure error report, I can log in successfully, but in my application I am always referred back to https://mysite/login with the error message: Login with Saml failed

in debug mode:
/customers/xxx/httpd.www/organisatie/src/AdvancedSecurity.php(596): Class "LightSaml\Meta\ParameterBag" not found

thanks for the help

Aftering enabling login with SAML, make sure you generate all files again and make sure composer update is done successfully to download the "litesaml/lightsaml" package, then upload the files and the updated "vender" folder to your site, otherwise the classes from the package will not be found.

regenerated everything and overwrote everything on the server, it works fine again. Thank you very much for the help!
