Registry Web UI: Logout results in Cognito error page

[aarora79]

Bug Description

When logging out from the Registry web UI, users encounter a Cognito error page displaying:

Invalid request
Please check your input and try again.

Expected Behavior

Users should be successfully logged out and redirected to an appropriate page (login page or home page) without encountering an error.

Actual Behavior

A Cognito error page is displayed with the message "Invalid request - Please check your input and try again."

Steps to Reproduce

1. Access the Registry web UI
2. Log in with valid credentials
3. Attempt to log out using the logout functionality
4. Observe the Cognito error page

Impact

This affects user experience and may cause confusion about whether the logout was successful.

Additional Context

This appears to be related to the logout request handling in the web UI component of the Registry, specifically with the Cognito authentication flow.
