If you want to enter without logging in, You can set your security to “off”. If you expect something else, comment below.
It depends on what you are trying to do. I see that you are calling the /SSO url. If you are trying to get SSO working, you need to configure the module's configuration settings and follow this guide to get it working the way you want it to: https://docs.mendix.com/appstore/modules/saml/.
If you just want a certain url, for example ‘/home’, to lead to the homepage of your app, then I would advise using the ‘Deeplink’ module from the Mendix Marketplace. With this module, you can run microflows when calling specific urls, which can for example open a page.
Hope this helps.
