Shibboleth IdP Upgrade from idp3 to idp 4

I'm currently working on upgrading our Shibboleth IdP from version 3 to version 4. After modifying the configuration files in IdP, we are encountering an issue with the SAML response. The error manifests as an HTML page displaying an "Uncaught Exception" message, as shown in the attached screenshot: Web Login-uncaught exception.Web Login-uncaught exception

Here is the relevant portion of the log file:

2024-07-29 12:50:12,576 - 127.0.0.1 - ERROR [net.shibboleth.idp.saml.profile:39] - Uncaught runtime exception

We made modifications to the Shibboleth IdP configuration files to align with our requirements for the upgrade from version 3 to version 4.

Our expectation was that these changes would enable the IdP to process SAML requests and generate valid SAML responses correctly, in compliance with SAML specifications. This would ensure seamless authentication and single sign-on (SSO) functionality for our users.

However, we are encountering a runtime exception related to the PopulateBindingAndEndpointContexts bean, which is preventing the IdP from generating the expected SAML responses.
