Troubleshooting Zen Exception error for SSO SAML login

Hello.  I'm wondering if anyone has experienced a similar error and if so, if they can point me in the right direction.  I have a client who is logging into Epic and is using the Epic SAML to single sign on to our HealthShare system.  We saw that it authenticated her through (from Epic to HealthShare) but when it attempted to open up the patient, we received the following Java error.  When she clicks OK, it keeps coming back.  Also, she is accessing Epic through a Citrix connection (if that helps with anything).  Here is the error below. 

Thanks!
