When there is an issue with the current session (invalid, expired session), the Clarity MUX login page displays an empty toast error message.
Steps to Reproduce:
Expected Results: An error is shown, as the session ID sent to Clarity is not valid (it is for CSA, but not Clarity).
In Classic login, the following error is displayed: 'CMN-01016: Your session has expired.'
Actual Results: An empty error message is shown.
This may also occur if a valid Clarity session expires due to a timeout and the MUX login page is displayed.
Clarity 16.4.0, 16.4.1
DE182716
This issue has been fixed in Clarity 16.4.2 (it now shows "Your session has expired.").
