Blank Error Message on vRSLCM 8.8.x when we check for System Upgrade

When you perform an upgrade to latest version of vRSLCM that's 8.8.2.3 and you perform a "Check for Upgrade" it would throw a red banner which looks like an exception with no message

This is a cosmetic issue and has no impact of product functionality

Ideally , when your on latest version of vRSLCM , then you perform a system upgrade check you would be returned that there is no upgrade available.

This is still the behavior in the background. Due to a known issue instead of a message we get an exception.

This behavior is being fixed in upcoming release of vRSLCM

From logs perspective , when you click on "check for upgrade" this is what happens in the background
