Hi All,I am getting below Error on Challenge ⌗9 of Data Integration Specialist.Challenge Not yet complete... here's what's wrong: There was an unexpected error in your org which is preventing this assessment check from completing: System.ExternalObjectException: This data is no longer available. The "Invoices" table in the external system is currently unavailable. Try again later or contact your administrator for help.Any help will be greatly appreciated.Thnaks ,
This probably means what it says... :) the external database became unavailable. Go to Setup-> External datasources and validate and sync again... If there are any problems check the URL again.Good Luck!
