With multi-domain configuration enabled for the OSP horizon dashboard, the customer experienced a UI crash when logging in as a domain admin. With multi-domain support enabled horizon incorrectly attempts to grant access to the list domains view within the UI which triggered a crash of the UI due to a logic bug in the error handling of the exception. Even as the exception was handled in 1688685, if we don't configure the system well, there will be errors and changing configuration on a live system is a hassle.
Verified this now on RHOSP15 in my server 10.35.160.195 UI doesn't crash anymore on multiple domains.
