Exception handling added for Redirect URL fetched from GRS

When the application definition under “integration and security" tab was configured to use "Store in web storage provider" to allow choosing the storage name and the authentication profile, configuring the authentication profile to use an OpenID connect provider with the pyEndpointURL property given as a global resource setting such as (=D_SharepointDetails.url) was not working as expected. Clicking browse in the application definition sent the request to the OpenID connect provider and was returned with the error "The reference =D_SharepointDetails.url is not valid. Reason: Page name (D_SharepointDetails) from indirect reference was not found." This was traced to the Redirect URL (fetched from GRS) throwing an unhandled exception, and has been resolved.
