[keycloak-user] Uncaught Exception: undefined in JavaScript client with check-sso

[Ryan Slominski]

Hi Keycloak Users,
   Looks like there might be a bug in the JavaScript client as the simplest use of onLoad: 'check-sso' seems to result in an Uncaught Exception.  Using Keycloak 4.1.0.  Simplest code snippet here:

Open web browser console (F12) and see Uncaught Exception.  Exception doesn't seem to break anything though and it appears to be safe to simply ignore it.  Remove check-sso and the exception goes away.  Should I file a bug issue on it?
