Hello,

I am facing an issue with lightning--

When I click the escalation/transfer button on the case object in the sandbox I am hitting an error

"Something has gone wrong. [NoErrorObjectAvailable] Access Check Failed! AttributeSet.get(): attribute 'transferQueues' of component
' is not visible to 'markup://c:QueueTransfer" . Below is the definition of button.
 

var ticketId = "{!Case.Id}";
var userType = "{!User.UserTypeFormula__c}";
var targetUrl = "/c/TicketTransfer.app#main?caseId="+ticketId;
window.location = (userType == "PowerPartner" ? "/partners" : "") + targetUrl;
