SimpleSamlphp InvalidArgumentError

[Andrew Asche]

Hi all,

I'm getting an error when trying to access the simplesaml Front Page. I haven't been able to access this page since I have started installing the simplesamlphp 2.0. I have a installation of simplesaml 1.19.6, but I haven't been able to get this simplesamlphp 2.0.6 working yet.

Error:

[critical] Uncaught PHP Exception InvalidArgumentException: "The controller for URI "/core/welcome" is not callable: Controller "SimpleSAML\Module\core\Controller\Login" has required constructor arguments and does not exist in the container. Did you forget to define the controller as a service?" at /<webserver directory>/simplesamlphp-2.0.6/vendor/symfony/http-kernel/Controller/ControllerResolver.php line 88

Any help or suggestions would be appreciated.

Thanks

Hello Andrew,

have you been able to find a solution yet? I am currently having problems with a similar issue and would be very grateful for a tip.

Thank you very much and best regards

I had to put the simplesamlphp folder in /var and not have it in the webserver folder.

I'm having the same problem as @Andrew, and I have no idea what's going on. This is my tenth installation using a CI script from Gitlab. The previous installations worked, and I was able to access both the welcome page and the admin page.

Backtrace: 2 src/SimpleSAML/Error/ExceptionHandler.php:36 (SimpleSAML\Error\ExceptionHandler::customExceptionHandler) 1 vendor/symfony/error-handler/ErrorHandler.php:538 (Symfony\Component\ErrorHandler\ErrorHandler::handleException) 0 [builtin] (N/A) Caused by: InvalidArgumentException: The controller for URI "/core/welcome" is not callable: Controller "SimpleSAML\Module\core\Controller\Login" has required constructor arguments and does not exist in the container.

My installation path is /var/www/simplesaml

My apache config is:

<Directory "/var/www/simplesaml/public">

    Options Indexes FollowSymLinks

    AllowOverride All

    Require all granted

    SetEnv SIMPLESAMLPHP_CONFIG_DIR /var/www/simplesaml/config

</Directory>

<IfModule alias_module>

Alias /simplesaml/ "/var/www/simplesaml/public/"
.....

Can someone please help?

What directory is your simplesamlphp in ? I think the documentation says where it should be. That is the fix I used
