If I try to navigate to any contact like this: https://workbench.developerforce.com/retrieve.php?id=XXXXX
I get the error: An existing Contact could not found with the id 'XXXX'. Confirm both the object type and id are correct.
I can view the contact just fine in Salesforce.
Navigating with the retrieve.php url works for other objects like opportunities. Is there perhaps an add-on module that is causing this to fail. I saw this error in the past and it was because my user did not have a license for an add-on.
Any way to troubleshoot this?
