User Receives "You Have Encountered An Unexpected Error..." When Searching Vendors

Hi,

On the Supplier page a user has begun receiving the error "You have encountered an unexpected error. Please contact the system administrator for assistance." (no other error text, no link to view error details) when trying to call up any vendor details.

The navigation path is Suppliers (entry of inquiry) > enter search > click View Details on a supplier > receive error message above.

Other users with the same responsibility do not receive this error.  We are on R12.2.3 .  We've tried clearing the browser cache and restarting the workstation but still the same error.  I suspect something with the user role may not be right.
