Read wxcorp/wxoaapi.go at lines 148-152 in commit d10c4839f7c97db7d7b9d215239b87421b3825ff, then inspect the range loop and NotifyApproval call. Determine whether the referenced loop variable can escape or be observed incorrectly, using the analyzer details as a starting point. Done means classifying the finding with the appropriate reaction.
