Symptoms

When trying to access K2 Designer URL, I got the below error.
=================================
Server Error

ID1032: At least one 'audienceUri' must be specified in the SamlSecurityTokenRequirement when the AudienceUriMode is set to 'Always' or 'BearerKeyOnly'. Either add the valid URI values to the AudienceUris property of SamlSecurityTokenRequirement, or turn off checking by specifying an AudienceUriMode of 'Never' on the SamlSecurityTokenRequirement.
