Error: “No such column” in Salesforce

When creating field mappings, you get an error in Salesforce that “No such column” exists on an object. The error may look like this:

No such column 'GetFeedback_Aut__Url__c' on sobject of type GetFeedback_Aut__Response__c

Make sure the user has permission to create, read, and update the field in Salesforce. If they don’t have permissions, the field is hidden and Salesforce shows the “No such column” error.
