Invalid array settings: idp_sso_url_invalid

[MasterPuffin]

Since a few days I have the following issue with the SSO plugin. I haven't changed the config. Here are the logs

[2024-06-16 22:25:23] production.ERROR: Invalid array settings: idp_sso_url_invalid {"exception":"[object] (OneLogin\\Saml2\\Error(code: 2): Invalid array settings: idp_sso_url_invalid at /var/www/vhosts/host/httpdocs/url_freescout/Modules/Saml/vendor/onelogin/php-saml/src/Saml2/Settings.php:141)

Your PHP version? Are you using any non-official modules or customizations?

[freescout-help]

On line 545 in /Modules/Saml/vendor/onelogin/php-saml/src/Saml2/Settings.php there is:

            } else if (!filter_var($idp['singleSignOnService']['url'], FILTER_VALIDATE_URL)) {
                $errors[] = 'idp_sso_url_invalid';
            }

It means something happened to "Signin URL" under "Identity Provider (IdP)". Check if the Signin URL visible on "Settings >> SAML 2.0" page and present in the .env file.

[MasterPuffin]

I'm using PHP 8.2 with only the SSO module and nothing else.

Here is the SAML config from the env file:

SAML_ENABLED=on

SAML_IDP_ENTITY_ID="https://saml.example.org"

SAML_IDP_SIGNIN_URL="https://www.example.org/auth/saml/freescout/"

SAML_LOGOUT_URL=

SAML_IDP_CERT="<cert>"

SAML_MAPPING="<mapping>"

SAML_AUTH_CONTEXT=

SAML_AUTO_CREATE_USERS=1

SAML_FORCE_SAML_LOGIN=1

SAML_DEBUG=

SAML_STRICT=1

[freescout-help]

You may need to debug this line to find out what value is contained in $idp['singleSignOnService']['url']: https://github.com/freescout-helpdesk/freescout/issues/4078#issuecomment-2172402953

[MasterPuffin]

The URL logged is https:///www.example.org/auth/saml/freescout/ whith three slashes instead of two, however the URL in the .env file is correct. Is the URL stored anywhere else?

[freescout-help]

It should be cached in /bootstrap/cache/config.php - check what you have there.

[MasterPuffin]

Deleting the file you mentioned fixed the issue. Thanks 👍

[freescout-help]

Ok. Strange.
